What the F 03 error code actually means
The F 03 code means your Electrolux dryer is running but not producing any heat. Something in the system that generates heat, whether electric or gas, has stopped working properly. Clothes will tumble but come out damp because there is no heat to dry them.

First diagnostic step
Touch the Stop/Clear pad to clear the F 03. Program the dryer for a NORMAL CYCLE with HIGH HEAT and touch START. Measure the voltage drop across the terminals of relay RL 2 on the electronic control board. If the meter reads 240 VAC on electric models or 120 VAC on gas models, replace the electronic control board. If the meter reads zero, remove power from the dryer and disconnect the black wire (electric models) or orange wire (gas models) from the relay. Reconnect power and measure the voltage drop between red wire on relay RL 2 to neutral. If zero, the wire between the incoming line and relay RL 2 is open. If 120 VAC, check the rest of the heating circuit.

Questions people ask about F 03
What does F 03 mean on a Electrolux dryer?
F 03 indicates a no-heat condition in the dryer's heater system. The control board has detected that the heating circuit is not operating correctly during a drying cycle. The code applies to both electric and gas Electrolux dryer models. Clothes will tumble but will not dry because no heat is being generated.
Is it safe to run my dryer when the F 03 code is showing?
Running the dryer with an active F 03 code means it is producing no heat, so clothes will not dry effectively. The dryer motor and drum will still operate. The more pressing concern is identifying the root cause, since a failed thermal fuse may indicate the dryer previously overheated, which should be investigated before continued use.
How do I diagnose whether the control board or the heating circuit is causing F 03?
Start by touching Stop/Clear, then program a NORMAL CYCLE with HIGH HEAT and press START. Using a multimeter, measure the voltage drop across the terminals of relay RL 2 on the control board. On electric models, a reading of 240 VAC points to a faulty control board. On gas models, 120 VAC at the relay terminals points to the same conclusion. A reading of zero directs you to check the supply wire and the downstream heating components including fuses, thermostats, the heating element, or the gas valve.
Can I reset the F 03 code and will it clear the problem?
You can clear the F 03 code by touching the Stop/Clear pad. However, clearing the code does not repair the underlying fault. If the heating system problem is not corrected, the code will return when you run another cycle with heat. Clearing it is useful as a first step to confirm the fault is active before beginning diagnosis.
How much does it cost to fix an F 03 error on an Electrolux dryer?
Repair costs depend on which component has failed. A thermal fuse or thermostat replacement is generally the least expensive repair, typically in the range of $20 to $80 for parts. A heating element or gas valve repair may run $50 to $200 in parts. Replacing the electronic control board is usually the most costly option, often ranging from $100 to $300 or more depending on the model, plus any labor charges.
