Answer to continue safely
Is it safe to keep using?
Maybe.
Can I reset the code?
Yes.
When to stop immediately?
Stop if you notice: The microwave door is stuck in the locked position and will not open, You hear continuous motor running or buzzing from the latch area that does not stop.
Symptoms You May Notice
Convection mode will not start or locks mid-cycle
Selecting a convection cooking program triggers E-22 because the motorized door latch cannot confirm engagement before the heating element activates.
Audible motor grinding when starting convection mode
A grinding or clicking sound comes from the latch area when the microwave attempts to lock the door for a convection cycle, indicating stripped gears.
Door remains locked after a cycle ends
The motorized latch does not release after cooking completes, leaving the door stuck in the locked position until the unit is powered off.
Standard microwave modes work but convection does not
Regular microwave heating operates normally because it does not require the motorized latch, but any mode needing the door lock triggers E-22.
Possible Causes
Stripped latch motor gear
The small plastic drive gear inside the latch assembly cracks or strips its teeth, preventing the motor from moving the latch bolt to the locked or unlocked position.
Requires ProfessionalFailed latch position switch
The microswitch that confirms the latch has reached its fully engaged or fully released position fails, preventing the control board from verifying the lock state even if the motor works.
Requires ProfessionalSeized latch motor
Grease buildup or bearing wear inside the small DC motor causes it to seize, drawing excessive current and failing to move the latch mechanism.
Requires ProfessionalSafe Checks You Can Do
-
1
Listen for the latch motor
Start a convection cycle and listen near the door latch area. Note whether you hear a motor running, grinding, or no sound at all when the lock should be engaging.
A motor that runs but does not move the latch indicates a stripped gear. No motor sound at all suggests an electrical failure.

Test standard microwave mode
Run a manual microwave-only cook cycle with a cup of water to confirm that the unit heats normally when the motorized latch is not required.
If standard microwave cooking works fine, you can continue using those modes while scheduling the latch repair.
When to Call a Professional
Contact a qualified technician if:
- The latch motor makes grinding sounds but the lock bolt does not move
- The door remains locked after the microwave is unplugged for ten minutes
- E-22 appears on every convection cycle attempt after power cycling
