Quick answer: Most Westinghouse fridge error codes point at a failed temperature sensor, fan motor or defrost part — not the control board. F1 and F2 are the common ones (a sensor fault, usually a $15–$40 fix), F5 means the defrost system isn’t completing, and the SY codes on French-door models flag communication or evaporator fan faults. We stock the sensors, fan motors and defrost parts from $16.85 to $45.95 AUD with same-day dispatch from our Sydney warehouse.

Westinghouse has the biggest fridge install base in Australia, and because the brand sits inside the Electrolux family, its fridges share error codes across a lot of chassis: the classic F-codes on side-by-side and top-mount models with electronic displays, and the SY-prefix codes on the newer Electrolux-platform French-door models. When one of those codes appears, the display is usually doing exactly what it should — reporting that one specific sensor, fan or defrost component has stopped answering.
That is good news for your wallet. Generic advice online jumps straight to “call a technician” or “the control board has failed”, but in the great majority of cases the board is fine and the fix is a small part: a thermistor, a fan motor, a defrost heater or a thermal fuse. This guide lists every code we’re confident is documented on Australian Westinghouse models, what each one means, and the exact part that clears it.
What do the error codes on a Westinghouse fridge mean?
Match the code on your display to the table below. Where a code has its own detailed guide, follow the link rather than guessing — F1 and F2 in particular have full step-by-step diagnostic pages.
| Code | What it means | Most likely cause | The fix / part |
|---|---|---|---|
| F1 | Fridge-compartment temperature sensor (thermistor) fault | Sensor open-circuit, shorted, or connector worked loose | Replace the fridge sensor — full guide: Westinghouse F1 error |
| F2 | Freezer or evaporator temperature sensor fault | Freezer thermistor or defrost-termination sensor dead | Replace the freezer/evaporator sensor — full guide: Westinghouse F2 error |
 F3 | Defrost / evaporator thermistor fault | Sensor dead, or ice built up on the probe | Defrost the coil, test the sensor, replace if out of range — defrost thermostat |
| F4 | Ambient (room) temperature sensor fault — newer models | Sensor dead or unplugged | Test and replace the ambient sensor — find your part |
 F5 | Defrost system not completing its cycle | Defrost heater, thermal fuse/DTT, or defrost thermistor failed | Thermal fuse & DTT assembly or defrost heater element |
| F7 | Communication fault between the main control board and the display | Loose harness between boards; board fault | Reseat the connectors; if it persists, have the boards checked — find your part |
| E1–E7 (WQE/WHE models) | Sensor, fan and defrost faults in the same family as the F-codes | Varies by model — the mapping differs between chassis | Check the code list for your exact model, then find your part |
| SY CE (French door) | Communication error between control boards | Loose or damaged wiring harness between boards | Power-cycle; reseat harness connectors; boards checked if it returns |
| SY CF (French door) | Display can’t communicate with the main control board | Harness or board fault | Power-cycle; if the code returns, board-level repair |
 SY EF (French door) | Evaporator fan circuit failure | Evaporator fan motor seized or iced up | Evaporator fan motor — match your model |
| OP (with compartment display) | Sensor circuit reading open (no signal) | Thermistor open-circuit or unplugged | Test the sensor for that compartment, replace if open |
| SH (with compartment display) | Sensor circuit reading shorted | Thermistor shorted, often moisture in the connector | Dry and reseat the connector; replace the sensor if it persists |
| Flashing temperature / high-temp alarm | Not a fault code — compartment got too warm | Power outage, door left ajar, or overloading | Check the door seal closes, let it pull down, alarm clears itself |
Two things stand out from that table. First, more than half of the codes are sensor faults — small two-wire thermistors that cost a fraction of a service call-out. Second, the codes that aren’t sensors are nearly all fan or defrost parts, which are also inexpensive and also replaceable. The control board is the last suspect, not the first.
F1 and F2 — the two codes Australians search for most
F1 (fridge-compartment sensor) and F2 (freezer/evaporator sensor) are by far the most common Westinghouse fridge codes, and each has its own full diagnostic guide on this site — the reset procedure, how to test the thermistor with a multimeter, and which sensor suits which chassis:
- Westinghouse fridge F1 error — what it means and the $15 fix
- Westinghouse fridge F2 error — freezer sensor diagnosis
The short version for both: the fridge keeps cooling (inconsistently) with the code showing, the sensor is the culprit far more often than the board, and the swap is a screwdriver job. If your display shows F1 or F2, go straight to those guides.
What should I check before ordering a part?
Work through these first. They cost nothing and they stop you replacing a part that was never faulty.
- Power-cycle the fridge. Switch it off at the wall, wait five minutes, switch it back on. A voltage spike or brown-out can latch an error code even when every component is healthy. If the code stays away for a day or two, it was a glitch.
- Check the door seals and the door. A door left ajar overnight, a perished seal or an overfilled crisper pushing the door open will trigger the high-temperature alarm and can drive the defrost system hard enough to throw codes downstream.
- Listen for the fans. Open the door, hold the door switch in (or check with the door closed if your model lets you) and listen. A healthy evaporator fan has a steady hum. Silence, or a grinding/chirping noise, points at a fan code (SY EF, or fan-related E-codes) and a fan motor swap.
- Look for ice where ice shouldn’t be. A sheet of ice on the back wall of the freezer, or frost migrating into the fridge section, means the defrost cycle isn’t completing — that’s F5 territory: defrost heater, thermal fuse/DTT or defrost thermistor.
- Reseat connectors before condemning parts. Sensor codes (F1–F4, OP, SH) are sometimes just a connector that has worked loose or picked up moisture. Unplug the fridge at the wall first, then check the relevant plug is home.
If the code comes back after a power-cycle and the checks above, the part named in the table is the overwhelming favourite. If your fridge has a cooling problem without any code at all, start with our Westinghouse fridge not cooling guide instead.

Is it safe to fix these faults myself?
Sensors and thermistors are low-risk: two wires and a clip, no capacitors, no refrigerant. Fan motors, defrost heaters and thermal fuses are mains-voltage components, so the rule is absolute: unplug the fridge at the wall before you remove a single screw. Don’t rely on the display being off, and don’t work on the defrost circuit with the cabinet powered.
If you’re a competent person who is comfortable disconnecting and reconnecting mains-voltage wiring, most of these swaps are 30–60 minute jobs with a screwdriver and a photo of the connectors before you unplug them. If any of it is outside your comfort zone — or the fault turns out to be board-level or refrigerant-related — hand it to a qualified appliance technician. Around the Sydney Northern Beaches plenty of tradies will happily fit a part you’ve already bought, which keeps the total cost right down.
One more safety note: never bypass a thermal fuse or a defrost termination thermostat to “test” the heater. Those parts exist to stop the defrost heater running unchecked. Replace them, don’t bridge them.
Frequently asked questions
What does F1 mean on a Westinghouse fridge?
F1 means the fridge-compartment temperature sensor (thermistor) has failed or come unplugged — the sensor is dead, shorted, or its connector is loose. The fridge still cools, but inconsistently. It’s usually a $15–$25 part and about 30 minutes of work. See the full Westinghouse F1 error guide.
How do I reset a Westinghouse fridge error code?
Switch the fridge off at the wall, wait five minutes, then switch it back on. That clears a code latched by a power glitch. If the code returns within a day or two, the component it names really does need attention — resetting again won’t fix the underlying part.
Where do I find the model number on my Westinghouse fridge?
Check the model sticker inside the fridge compartment — usually on the side wall near the crisper bins, or just inside the door opening. Look for a code like WSE6100WF, WTB5400SA or WQE6000SB, then match it to the parts table above or run it through the part finder.
Can I still use the fridge while an error code is showing?
Usually yes, for a few days. With a sensor code (F1–F4) the board falls back to a safety cycle, so cooling continues but less accurately — don’t leave it for weeks or you risk food loss. With a defrost code (F5) or a fan code (SY EF), ice builds up and cooling degrades faster, so treat those with more urgency.
What does SY CE mean on a Westinghouse French-door fridge?
SY CE is a communication error between the control boards on the Electrolux-platform French-door models. Power-cycle the fridge at the wall first; if the code returns, the wiring harness between the boards needs reseating or a board needs professional attention. It is not a sensor or fan fault, so don’t start replacing those.
Do Westinghouse and Electrolux fridges share error codes?
Largely, yes. Westinghouse is part of the Electrolux family and many Australian models share platforms, so the F-code sensor family and the SY-prefix French-door codes carry across related Electrolux-built cabinets. Always confirm parts by your exact model number from the model sticker, not by the code alone.
How much do the parts cost and how fast do they ship?
The parts that fix the common codes run from $16.85 to $45.95 AUD — sensors and defrost thermostats at the bottom of that range, fan motors at the top. Everything in the table above is in stock in our Sydney warehouse and ships same day when you order before cut-off.
Clear the code and keep the fridge
A Westinghouse error code is a diagnosis, not a death sentence. Match the code to the table, do the free checks, and in most cases you’re up for a sensor, fan or defrost part under $50 — not a new fridge.
