Oven door won't open/close smoothly? Check hinge arm position with door fully open - slight misalignment prevents proper hinge lock engagement. Adjust hinge position before replacing door
repair_tip
The oven racks have specific slots on the range - using wrong-sized racks or over-loading racks can cause binding and oven door misalignment. Always verify correct rack size for the cavity before reassembling.
Door Lock Micro Switch Test
The door locking micro switch should be Normally Closed when the door is in the unlocked position (COM-NC). When door is locked, switch opens. Improper state indicates micro switch failure or mis-alignment of door latch assembly.
Steam Leakage Around Door
Customers report steam leaking from the door or seeing water on the control panel. 90% of the time it's not the door gasket or oven sealing - it's steam condensing on the outer oven surface and running down. This is actually normal. The remaining 10% is from a bent door caused by user pushing too hard when closing or allowing heavy cookware to fall against it. Measure door alignment before assuming seal failure.
