Don A for Model Number gh5184xp
Answer Hello Don,
Microwave will not operate (cook). F7 error codeappears on the display indicates a electrical circuit interruption between L1 and Neutral in
the microwave inverter circuit. Possible reasons:
1. Check door, hinge and cavity front alignment and adjust
as needed.
2. Check the operation of all interlock switches.
3. Check over temperature protector for the magnatron.
4. Check all Cavity Thermostats for closed circuit.
5. Unplug the oven for at least 40 seconds. If this solves the problem
A. Check the Cooling Fan for proper operation orblockage
B. Check the resistance of the magnetron thermostat. It should be 0 Ohms, replace if necessary.
6. Check that the control cable to the 1100 watt inverter is properly connected to plug P2 on the display PCB & Adjust or Reconnect
7. If interlock switches operate correctly, replace 1100W inverter.
8. If problem persists, replace control assembly.
Microwave gives error code "F7" after 2 seconds. Once remain on.

Hope this helps.
My model calls for part number AP2929268. I'd like to know what's difference between that one and this part number AP3881382?
