Product Description

This repair service is for a Magic Chef, Norge, Crosley, Admiral, or Maytag oven control board part number 3807F439-51 and relay control board, WP74001870, that have failed and are experiencing one or more of the following issues:

  • Error codes including F1 and F3
  • Intermittent operation
  • Oven exceeds the temperature setpoint or will not turn off - Requires repairing both the main control board AND the relay board, part number WP74001870 (select option above).
  • The oven does not reach temperature - Requires repairing both the main control board AND the relay board, part number WP74001870 (select option above).

It is our professional recommendation that you rebuild both boards at the same time because:

  1. Repairing both boards will correct all the issues listed on this page.
  2. It allows all of the oven's electronic control board components to be rebuilt using upgraded components.
  3. It will significantly extend the life of the oven with trouble-free operation.
  4. You can take advantage of discounted package repair pricing. 
  5. Prevent future re-work and additional shipping costs later.
