Speed Queen Dryer Error Code HEAT ERROR

On a gas Speed Queen dryer, HEAT ERROR means the Ignition Control Module attempted to ignite the burner multiple times and failed after exhausting all programmed retry attempts. On an electric Speed Queen dryer, it means the control board detected that the heat contactor is shorted. Both conditions indicate a failure in the primary heating system that requires diagnosis before the dryer can safely run a full cycle.

On electric models, a shorted heat contactor can cause the heating element to remain energized outside of normal operation, which is a potential safety concern. The dryer should not be operated until the contactor has been inspected and replaced if necessary. On gas models, the unit failed to ignite but the fault itself does not indicate an unsafe condition in the same way, though the heating system still needs to be repaired before normal operation.

Repair costs vary depending on which component has failed and whether you hire a technician. Parts such as an igniter or gas valve coil kit typically range from $20 to $80, while an ICM or heat contactor can range from $50 to $150 or more depending on the model. Professional labor for a heating system diagnosis and repair commonly adds $100 to $200 on top of parts costs.

On gas models, the HEAT ERROR can be cleared by pressing a key, opening and closing the loading door, or cycling power to the unit. On electric models, the fault is treated as a more serious condition and can only be cleared through a full power cycle, use of the Clear Fatal Error key sequence, or a network command. Simply resetting the error without addressing the underlying problem will cause it to return.

Start by checking the igniter, gas valve coils, and the ICM for faults. Confirm that the gas supply valve is fully open and that gas pressure is adequate. Test the flame sensor for proper function, as a faulty sensor can prevent the ICM from confirming a successful ignition even when a flame is present. Replace any components that fail testing, then clear the error and run a test cycle to confirm the repair.
