GE Range Error Code F33

F33 on a GE range signals a warming drawer sensor failure that occurred while the warming drawer was actively in use. The control board monitors the drawer's temperature sensor continuously, and if it receives an invalid or absent signal for 20 seconds, it triggers F33. The warming drawer circuit is typically disabled until the issue is resolved. The fault points to the sensor, its wiring, or in rare cases the control board.

The main oven and cooktop burners are separate from the warming drawer circuit, so they may continue to function normally while F33 is present. However, the warming drawer should not be used until the sensor fault is diagnosed and repaired, since the control board cannot regulate drawer temperature without a functioning sensor. Continuing to use a heating element without temperature feedback creates a potential overheating risk.

Repair costs depend on which component has failed. A warming drawer temperature sensor typically costs somewhere in the range of $20 to $60 for the part, while professional labor to diagnose and replace it can add $75 to $150 or more depending on your area. If the control board is at fault, board replacement costs generally range from $150 to $350 or higher for parts alone. Getting a diagnostic visit from a technician before purchasing parts is usually advisable.

Some causes of F33 are DIY-friendly, such as reseating a loose wiring connector or cleaning corroded pins at the sensor harness. However, replacing the warming drawer sensor or control board requires comfort working around electrical components and disassembling part of the range. If you are not experienced with appliance repair, a qualified technician is the safer choice.

Resetting the range by cutting power at the breaker for a few minutes may temporarily clear the F33 code, but if the underlying sensor or wiring problem still exists, the fault will return once the warming drawer is turned on again and the 20-second threshold is reached. A reset alone is not a repair. The root cause must be identified and corrected for the error to stay cleared.
