F5E1 Serious Moderate DIY

Maytag Microwave F5E1 — Door Switch Fault

Maytag Microwave · Error code F5E1

What F5E1 Means

The control detects that the door switches are not changing state correctly — typically one switch open while the others indicate door-closed, or vice versa.

Symptoms

  • F5E1 displayed when door opens, closes, or during cooking
  • Microwave will not start
  • Light stays on or fails to come on with door open
  • Door appears closed but unit thinks it's open

Common Causes

1
Failed primary or secondary interlock switch

One of the three door switches has welded contacts or broken plunger.

2
Door alignment / hinge wear

Door not pressing switches in the correct sequence.

3
Door switch wiring loose

Spade connector slipped off a switch terminal.

4
Failed monitor switch

Safety monitor switch detected an interlock failure and tripped.

How to Fix It

  1. Unplug the microwave — door switch faults can leave the monitor circuit armed.
  2. Inspect the door for sag, misalignment, or worn hinges; adjust or replace if loose.
  3. Remove the cabinet and locate the three door switches (primary, secondary, monitor).
  4. Test each switch for continuity with a multimeter — operate the plunger manually.
  5. Replace any switch that fails the continuity test; replace all three as a set if the monitor switch tripped.
  6. Verify wiring harness connections are fully seated.
  7. If a monitor switch tripped, also inspect the door fuse (line fuse) — it commonly blows.
  8. Reassemble and test door operation before restoring power.
