GE Profile Air Fryer: Check Fan Error - Troubleshooting... | appliancefaults.com

Technical Background:

The MCU (Microcontroller Unit) on the oven control board monitors the convection fan motor speed via a feedback circuit. If the MCU detects that the fan is not operating within the expected parameters, it triggers the 'Check Fan' error. Voltage is supplied to the fan via a relay on the control board. A temperature sensor is also involved in the logic.

Symptoms:

The GE Profile range displays a 'Check Fan' error and beeps five times when attempting to use the Air Fry mode. The convection fan may not be running at all, or it may run intermittently. The oven may not heat properly during the Air Fry cycle.

Possible Causes:

Convection fan motor failure.
Wiring harness damage to the convection fan.
Oven control board malfunction.
Blocked convection fan blades.
Thermostat issue affecting fan operation.
Faulty relay on the control board.

Solution:

1

Disconnect power to the range at the breaker panel.
2

Locate the convection fan, typically at the rear of the oven cavity. Access may require removing the rear panel of the range with a 1/4-inch nut driver.
3

Visually inspect the fan blades for obstructions. Remove any debris that may be blocking the fan's movement.
4

Disconnect the wiring harness to the convection fan motor. Use a small flat-head screwdriver to release the connector lock.
5

Using a multimeter, check the fan motor winding for continuity. A normal reading is typically between 40-120 ohms. An open winding indicates a failed motor. A short circuit indicates also motor damage.
6

Verify 120V AC is reaching the fan motor during the Air Fry cycle. Use extreme caution when measuring live voltage. If voltage is present and the fan is not running, replace the fan motor.
7

If no voltage is present, inspect the oven control board for burnt components or damaged relays. Replacing the oven control board may be necessary.

Safety Warning:

Always disconnect power to the range at the breaker panel before performing any repairs. Lock Out/Tag Out (LOTO) procedures should be followed to prevent accidental re-energizing of the circuit. High voltage is present inside the range. Exercise caution to avoid electrical shock.

Prevention:

Regularly clean the oven interior to prevent food debris from accumulating and potentially blocking the convection fan. Avoid using excessive force when cleaning near the fan blades. Check periodically for loose wiring connections.

Expert Tip:

Some GE Profile ranges have a service mode that allows you to manually activate the convection fan for testing purposes. Consult the service manual for instructions on entering service mode. This can help isolate the problem to the fan motor or the control board.

Frequently Asked Questions

•What is the part number for the convection fan motor on this model?

The part number for the convection fan motor varies depending on the specific sub-model. It's best to check the appliance's parts diagram using the full model number on the GE Appliance website or a reputable parts supplier.

•How do I access the oven control board?

The oven control board is typically located behind the control panel. You'll need to disconnect power, remove the screws securing the control panel, and carefully detach the panel to access the board. Be mindful of ribbon cables.

•If the fan motor tests good for continuity, what else could be causing the 'Check Fan' error?

If the fan motor has continuity and the wiring is good, suspect the relay on the control board is failing to provide voltage or the temperature sensor is providing incorrect data to the control board.
