Convection fan motor open — convection fan does not operate for cumulative 1 minute during convection fan operation period

Moderate

Address soon - your appliance may not work properly

What This Means

Failed convection fan motor (open windings); Fan motor relay shorted or failed; Loose or disconnected wiring to convection fan motor

How to Fix

  1. 1

    Unplug the unit

  2. 2

    Measure resistance of convection fan motor windings — Fan High winding: approximately 25 ohms +/- 10%; Fan Low winding: approximately 30 ohms +/- 10%; if infinite (open) or below 5 ohms (shorted), replace the fan motor

  3. 3

    Check fan motor relay resistance at Relay PCB CN53: Fan High relay — measure 5th and 7th pin of CN53 (RY8); Fan Low relay — measure 3rd and 7th pin of CN53 (RY9); normal is infinite (open); if shorted, replace the Relay PCB

  4. 4

    Check all connectors and harnesses associated with the convection fan for loose or disconnected connections; reconnect if loose

  5. 5

    If connectors are good and motor and relays test normal, replace the Main PCB
