TROUBLESHOOTING CONVECTION-OVEN BLOWER

WARNING

Before attempting to service or replace any electrical component, make sure power source has been disconnected.

CAUTION

When changing motor or servicing range, always verify that blower wheel rotation is clockwise when looking into the oven cavity.

The motor is serviceable from the front of the range through the oven cavity. Remove the back lining. Disconnect the motor mount plate by removing the eight hex nuts that secure it to the oven interior back. Pull the mount plate, with motor attached, into the oven.

Motor lubrication information can be found on permanent label located on motor.

If the blower does not run at all, consult the flowchart that begins on the next page. If the blower runs intermittently, consult the flowchart on this page.

The appropriate wiring diagram for the oven can be found on the rear of the oven (as well as at the end of this section of this manual).

DISCONNECT POWER AT CIRCUIT BREAKER.

Check all wiring for loose connections or breaks.

Remove the cover from the junction box on the back of the range. Disconnect the black wire and place an ammeter in the circuit.

CAUTION: Check that the ammeter is rated for at least 40 amperes! Reconnect the power to the range and turn on the blower switch while watching the ammeter. The reading should surge and then return to the rated current of the motor when running at high speed. If the measured current exceeds the motor rating, replace the blower motor.

Check that there are no air-flow obstructions around the range.

Check that the blower motor is not pressing against the wall

behind the range.

Check that the blower motor air vents are not obstructed.

Check for excessive grease and dust buildup on the motor.

Check for sources of excessive heat behind the range.

Check for hot-air leaks around the motor pocket.

With the blower turned ON, turn the oven thermostat to OFF and allow the oven to cool. If the blower motor runs continuously when the oven is cool, turn the oven thermostat to the highest setting. If the blower motor shuts off when the oven becomes hot, and if there are no sources of excessive heat around the blower motor, replace the blower motor.
