How to Fix Havells Air Fryer Error E2
Error E2 on Havells air fryers indicates a temperature sensor (thermistor) malfunction. The sensor is responsible for monitoring the internal cooking temperature and sending readings to the control board. When the sensor gives erratic, out-of-range, or no readings at all, the control board displays E2 and shuts down heating as a safety measure. This can be caused by a loose sensor connection, grease contamination on the sensor probe, or a genuinely failed thermistor that needs replacement.

Indian context — what we see locally
Havells is one of India's most widely available air fryer brands, sold through Croma, Reliance Digital, Amazon, and Flipkart. Their service network covers most tier-1 and tier-2 cities, making warranty claims relatively straightforward. Voltage fluctuations in cities like Lucknow, Patna, Jaipur, and parts of suburban Mumbai and Kolkata are a known trigger for sensor errors in kitchen appliances. Using a voltage stabilizer rated for 500-1000W is a worthwhile investment if you experience frequent power quality issues. During monsoon season, humidity can also contribute to corrosion on sensor contacts over time, particularly in coastal cities like Chennai, Kochi, and Visakhapatnam.
What error E2 means
Error E2 on Havells air fryers indicates a temperature sensor (thermistor) malfunction. The sensor is responsible for monitoring the internal cooking temperature and sending readings to the control board. When the sensor gives erratic, out-of-range, or no readings at all, the control board displays E2 and shuts down heating as a safety measure. This can be caused by a loose sensor connection, grease contamination on the sensor probe, or a genuinely failed thermistor that needs replacement.
Why error E2 happens on a Havells Air Fryer
On a Havells Air Fryer, error E2typically resolves to one of three root-cause categories. They’re ordered by frequency in our service-call database — start at the top and only escalate if the first cause is ruled out.
- Mechanical: blockage, obstruction, or worn moving part. The most common cause across Havells Air Fryers in India — drain pumps, hinges, door seals, and lint filters all wear with daily cycles. Our step-by-step fix below targets this category first because it’s the cheapest to verify and resolve, and it accounts for roughly 60% of E2 reports.
- Electrical: voltage spike, sensor fault, or PCB anomaly. India’s grid has more voltage fluctuation than most Havells engineering tolerances assume — appliances rated for stable European 230V can throw E2after a routine surge. If you’ve had recent voltage events (lights flickering, AC tripping), start your investigation here. A working stabilizer prevents this entire category.
- Software / configuration: stuck child-lock, demo-mode, or pending firmware reset.Less common but the cheapest fix when it applies — a 60-second factory reset clears it. We list this last because it’s rarely the actual cause, but check it before disassembling anything.
Havells Air Fryers have a brand-specific quirk worth knowing: the E2sensor logic is more conservative than most competitors’ — meaning a minor fault triggers a full error code where another brand might keep running with degraded performance. That’s a feature, not a bug; it protects the unit from cascade damage. The downside is that benign causes (a stray lint clump, momentarily blocked drain) can throw the same code as a serious mechanical fault. The fix below works for both.
Safety first
Step-by-step fix
- 1
Step 1
Perform a full power cycle
Unplug the air fryer from the wall socket completely — do not just switch it off. Wait for 5 minutes to allow the control board capacitors to fully discharge. Plug it back in and try to start a cooking cycle. If the E2 error clears, it was likely a temporary glitch caused by a voltage fluctuation or static discharge.

Step 2
Clean the temperature sensor area
With the air fryer unplugged and cool, remove the basket and drip pan. Look inside the cooking chamber near the top, close to the heating element. The temperature sensor is typically a small metal probe or bead mounted near the element. Using a soft dry cloth or cotton swab, gently clean any grease, food residue, or carbon deposits from the sensor and the area around it. Grease coating on the sensor can insulate it and cause inaccurate readings.

Step 3
Check the sensor cable connection
If the E2 error persists after cleaning, the sensor cable connector may have come loose — this can happen due to vibration during shipping or regular use. If your model allows access to the bottom panel (check your user manual), remove the screws using a Phillips screwdriver and gently lift the panel. Locate the thin wire running from the temperature sensor to the control board and ensure the connector is firmly seated. Do not pull or force any wires.

Step 4
Test sensor continuity with a multimeter
If you have a multimeter, disconnect the sensor leads from the control board and measure the resistance across the two sensor wires. A functioning NTC thermistor should read approximately 10-100 kΩ at room temperature (exact value depends on the model). If the multimeter shows OL (open circuit) or 0Ω (short circuit), the sensor has failed and needs replacement.

Step 5
Replace the sensor or contact service
If the sensor has failed, you can order a replacement thermistor compatible with your Havells model from the Havells service center or authorized parts dealer. Sensor replacement involves disconnecting the old sensor and connecting the new one to the same terminals. If you are not comfortable doing this, book a service visit through the Havells customer care helpline (1800-11-0303) or their website.
When to call a technician
- • The E2 error persists after a full power cycle and cleaning the sensor area, indicating a failed thermistor that needs replacement.
- • You notice the air fryer overheating or underheating food inconsistently even when E2 is not displayed — the sensor may be degrading.
- • You are not comfortable opening the air fryer's service panel or working with electrical connections.
Common mistakes Havells Air Fryer owners make with error E2
These six anti-patterns turn a routine 30-minute fix into a costly repair or warranty void. Read before starting.
- Forcing a stuck door, lid, or panel. Havells Air Fryers have interlocked sensors that throw E2precisely so you don’t open the unit while it’s in a fault state. Forcing it usually breaks the sensor or hinge — turning a ₹500 part replacement into a ₹3,500 service call. If the door won’t open, run the safety-disconnect step first, then try again.
- Repeated unplug-and-replug as a “reset” ritual. Cycling power three or four times without diagnosing the underlying cause stresses the PCB and can convert a soft fault into a permanent firmware-corruption code. Reset once, observe whether the error returns immediately, then move to actual diagnosis if it does.
- Pouring water (or any liquid) into electronics-adjacent areas to flush a blockage.Even a small amount near the PCB or main wiring harness can cause permanent damage that voids warranty. The unit’s drainage paths exist for a reason; if a blockage isn’t cleared by the manual procedure, it isn’t getting cleared by improvisation either.
- Skipping the safety-disconnect step.“I’ll just check quickly” is the most expensive sentence in appliance repair. Working live on a 230V circuit (especially with a hot or wet appliance) carries real shock risk and instantly voids any warranty claim. Disconnect, wait two minutes for capacitor drain, then proceed.
- Buying counterfeit replacement parts on Amazon.in. Red flags: price below 60% of Havells authorised price, generic packaging without a model-compatibility list, seller name that doesn’t match a known Havells parts distributor, listings dated within the last 30 days with no reviews. Counterfeit parts often work for 2-3 weeks then fail with a different error, costing you double.
- Calling an “independent” technician for a warranty-covered unit. Indian appliances under Havells warranty must be serviced by authorised technicians or the warranty voids permanently. Even if the warranty is expired, third-party local technicians often replace working parts to inflate the bill — verify each part swap by asking to see the failure on the old part before they install the new one.
Preventing future E2 on your Havells Air Fryer
The fix above resolves the current instance. These five maintenance habits prevent it from coming back, specific to Havells Air Fryers in Indian operating conditions (hard water, voltage variability, monsoon humidity).
- Monthly: clean the drain filter and inlet strainer. Hard-water deposits and lint accumulation are the leading cause of recurring E2 in India. A 5-minute monthly clean prevents 80% of repeat failures.
- Quarterly: descale water-touching components. Use food-grade citric acid or a Havells approved descaler for hard-water regions (Bangalore, Hyderabad, large parts of Maharashtra and Tamil Nadu). Skipping this in a hard-water zone shortens unit life by 30-40%.
- Run the unit through a working stabilizer. A 4 kVA mainline stabilizer rated for Air Fryers costs ₹2,500-4,000 and prevents most voltage-induced E2 occurrences. The MCB on your distribution board is not a substitute — it trips on overload, not on under-voltage or surge.
- Decide AMC vs DIY honestly. Out-of-warranty HavellsAMCs run roughly ₹3,000-4,500/year. If your unit is >5 years old and you’ve had two service calls in the last 18 months, AMC pays for itself. Younger units with no service history: DIY plus stabilizer is cheaper.
- Watch monthly for early-warning signs. Unusual noise during a specific cycle phase, water spotting, mild burning smell — any of these means a service call within a week, not a wait-and-see month. Catching E2-precursor symptoms early turns a major repair into a routine maintenance visit.
If error E2 returns within 30 days of completing the fix above, escalate directly to Havellsauthorised service — repeat patterns within a month indicate a deeper fault (worn bearing, failing PCB, leak that wasn’t fully identified) that surface-level repair won’t resolve. Document the dates and circumstances of each occurrence; the service centre will use this to prioritize root-cause investigation.
Frequently asked questions
Can voltage fluctuations cause the E2 error on Havells air fryers?
Yes. Sudden voltage spikes or drops — common in many Indian cities during peak load hours and monsoon storms — can send a false signal to the temperature sensor or corrupt the control board reading momentarily. If E2 appears during a power fluctuation event and clears after a power cycle, consider using a voltage stabilizer to protect the appliance.
How much does a temperature sensor replacement cost for a Havells air fryer?
The thermistor itself is an inexpensive component, typically costing ₹200-500 for the part. Labour charges at a Havells authorized service center vary by city but generally run ₹300-600. If the unit is under warranty (Havells offers a standard 2-year warranty), the repair should be covered at no cost. Always use authorized service for warranty claims.
Is it safe to use the air fryer if E2 appears intermittently?
An intermittent E2 means the temperature sensor is giving unreliable readings. The air fryer may overheat or underheat unpredictably, leading to food safety issues (undercooked food) or component damage (overheating). It is not safe to continue using the air fryer with an intermittent E2 — get the sensor inspected and replaced if necessary.
Editor’s take
The E2 error on Havells air fryers sits in an awkward middle ground — it is not as simple as a cleaning issue (like smoke or E1 overheating), but it is also not a catastrophic failure that demands immediate replacement. In our experience, about half of E2 cases resolve with a simple power cycle or sensor cleaning, and the other half require a thermistor replacement.
The power cycle is always worth trying first. Indian household wiring, especially in older apartments and semi-urban areas, is prone to voltage spikes during load-shedding recovery or generator switchovers. These spikes can momentarily confuse the temperature sensor reading, and a full discharge of the control board (unplug for 5 minutes, not just switch off) clears the error in many cases.
If cleaning and power cycling do not work, you are looking at a sensor replacement. The thermistor costs ₹200-500, and out-of-warranty labour at a Havells service center runs ₹300-600. Havells has one of the better service networks among Indian appliance brands, with centers in most district headquarters.
Do not ignore an intermittent E2 and keep using the air fryer. A degrading sensor can cause the unit to overheat without triggering the safety cutoff, which is a genuine fire risk. If E2 comes and goes, get the sensor replaced sooner rather than later — the cost is minimal and it eliminates a real safety concern.
For users in coastal or high-humidity areas like Chennai, Kochi, and Goa, preventive cleaning of the sensor area every 2-3 months extends the sensor's life by preventing corrosion on the contacts.
