Fridge
E1
The E1 error code on a Haier fridge signals a fault with the fridge compartment’s temperature sensor — specifically, the sensor is either reading an implausible temperature or has stopped communicating with the control board altogether. It’s one of the more common Haier fault codes and, while it sounds alarming, it’s not always a serious or expensive fix. In this guide you’ll learn exactly what’s triggering the E1 code, which causes you can rule out yourself at home, and when it’s time to call in a professional.
What does this error mean?
On Haier fridge-freezers and standalone fridges, the E1 error code indicates a fault with the NTC (Negative Temperature Coefficient) thermistor in the refrigerator compartment. This is a small, inexpensive sensor — typically clipped to the evaporator or mounted on the inner back wall — that continuously monitors the internal temperature and feeds that data to the main control board. When the board receives a reading that falls outside its accepted range (usually due to a short circuit, open circuit, or sensor failure), it throws the E1 code and may reduce cooling or shut the compressor down as a precaution. In plain terms: your fridge has lost confidence in its ability to accurately read its own temperature, so it’s flagging the problem rather than silently running at the wrong temperature and spoiling your food.

🔍 Likely causes
🛠️ Step-by-step fix
Step 1 — Power cycle the fridge first: Unplug the fridge from the wall socket (or switch off at the fuse spur), wait a full 10 minutes, then plug it back in. A surprising number of E1 codes are caused by a temporary communication glitch and will clear after a proper reset. Watch the display for 15–20 minutes to see if the error returns.
Step 2 — Check the door seal for damage: Run your fingers slowly around the entire perimeter of the fridge door gasket, feeling for tears, gaps, or sections that have gone stiff and no longer flex. You can also close the door on a piece of paper — if you can pull it out without resistance, the seal is failing. A replacement Haier door seal costs around £15–£30 and fits without tools on most models.
Step 3 — Inspect the inside of the fridge for excessive ice build-up: Remove all shelves and the salad drawer to look at the rear interior wall. If you can see a thick layer of frost or ice (more than a few millimetres), the evaporator is icing over and may be smothering the sensor. Empty the fridge, leave the door open, and allow a full manual defrost over 24 hours — place towels down to catch the water.
Step 4 — Locate and visually inspect the temperature sensor: On most Haier fridge models, the NTC sensor is a small, bullet-shaped probe clipped to the back wall of the fridge compartment or attached to the evaporator fins. You do not need to open any panels to see it. Look for visible damage: cracked casing, corrosion, or the sensor having come unclipped from its mount. Re-seat it firmly if it has simply come loose.
Step 5 — Check the sensor wiring for obvious damage: Trace the thin wire from the sensor towards the back panel. Look for any kinks, cuts, or areas where the wire appears pinched or has been chafed by a shelf bracket. Do not pull or force the wire. If the wiring looks intact, this step is clear.
Step 6 — Test the sensor resistance with a multimeter (DIY-confident users only): If you own a basic multimeter (available from Screwfix or Amazon for around £10–£20), unplug the fridge, gently unplug the sensor connector, and test resistance across the two sensor pins. At room temperature (around 20°C) a healthy Haier NTC sensor should read approximately 5,000–10,000 ohms (5–10 kΩ). A reading of 0 (short circuit) or OL/infinite (open circuit) confirms the sensor has failed and needs replacing.
Step 7 — Replace the NTC temperature sensor: Replacement Haier NTC sensors are widely available from UK spares suppliers such as eSpares, 4ourhouse, and buyspares.co.uk. Search for your full model number (printed on the label inside the fridge door frame) to get the correct part — expect to pay £8–£20. The sensor typically unclips and unplugs with no tools required. Plug in the new sensor, refit the clip, restore power, and check whether the E1 code has cleared.
Step 8 — Reset the fridge after fitting the new sensor: Some Haier models require a manual reset after a sensor replacement. Hold the ‘Alarm’ or ‘Set’ button (depending on your model) for 5 seconds to clear stored fault codes, or simply unplug for 10 minutes again. Consult your model’s manual on the Haier UK support website if you are unsure which buttons to use.
Step 9 — If the error persists after sensor replacement, stop DIY here: If you have replaced the sensor with a confirmed correct part and the E1 code returns within a few hours, the fault is most likely with the main control board or an internal wiring harness — both of which require professional diagnosis. Do not attempt to open the appliance’s sealed electrical panels yourself.
📞 When to call a professional
You should stop DIY attempts and call a qualified appliance engineer if: the E1 error returns after a full power reset and a confirmed-correct sensor replacement; the wiring harness between the sensor and control board appears damaged or burnt; there is any evidence of refrigerant leakage (oily residue near pipe connections, the fridge is warm but the compressor is running continuously); or the fridge is completely failing to cool even though the compressor sounds like it is running. When you call, tell the engineer: ‘My Haier fridge is showing an E1 error code, which I understand relates to the fridge compartment NTC temperature sensor. I have already power-cycled the unit and [replaced the sensor / inspected the wiring — delete as applicable] but the fault has returned.’ This saves diagnostic time and money. Look for an engineer registered with the Domestic Appliance Service Association (DASA) or one who specifically lists Haier appliance repair. Haier UK also operates a direct customer service line and can arrange authorised engineer visits for appliances still under their standard 2-year or extended warranty.
⚖️ Repair or replace?
For most UK homeowners, repairing an E1 fault is well worth doing — provided the fridge is under 8 years old and has not had multiple previous faults. If the fix is simply a new NTC sensor (the most common scenario), you are looking at a £8–£20 part and 15 minutes of your time, which is almost always worthwhile regardless of the fridge’s age. If the fault has escalated to a control board replacement, costs rise to £80–£180 for parts plus £60–£100 for a call-out, bringing total repair costs to £140–£280. At that point, compare against the cost of a comparable replacement fridge: a decent Haier fridge-freezer currently retails between £350 and £800 in the UK depending on size and specification. The general rule of thumb is: if the repair costs more than 50% of the replacement value, and the fridge is over 7–8 years old, replacing is the smarter financial decision. Haier spares availability in the UK is reasonably good for models sold in the last 5 years — HTF and HB series parts are stocked by major UK spares retailers — but older or grey-import models can be harder to source parts for, which tips the balance further towards replacement.
