Common failure areas on this model
The confirmed parts above group into a handful of failure areas. Here is what each points to and how to check it before you order anything.
General hardware and mounting parts
Symptom: A small mechanical or mounting part has failed, cracked, or gone missing.
Check: Compare the physical shape and mounting points to the original piece, and confirm the exact part number against your model plate before ordering.
Parts in this group on MDE7400AYQ: WP33002725 (4-Position Rotary Temperature Switch), 33001755 (Dryer Drum Baffle), 306106 (Holding Coil), 306105 (Second Coil), 303377 (Gas Sensor), 312958 (Lock Ring, I).
Drive system (belts, pulleys, motors)
Symptom: A drum or tub that won't turn, a burning-rubber smell, or a loud thump or squeal during a cycle.
Check: With power off, turn the drum or tub by hand -- resistance or grinding points to the motor or a bearing, and a cracked, glazed, or snapped belt is visible once the cabinet is open.
Parts in this group on MDE7400AYQ: 33002535 (Dryer Drum Belt), 303373 (Roller W/bea).
Interior lighting
Symptom: The interior light doesn't turn on when the door opens.
Check: Confirm power is reaching the socket, then check the door-activated light switch before assuming the bulb itself is at fault.

Heat control (thermostats, fuses, heating element)
Symptom: The dryer runs but produces no heat, or it shuts off partway through the cycle.
Check: With the dryer unplugged, check continuity across the part with a multimeter -- no continuity means it has failed. Clear the lint vent first, since a blocked vent is what usually trips a thermal fuse in the first place.

Before you buy
Match MDE7400AYQ exactly against the model and serial plate on the appliance itself before ordering anything — a single mismatched character can point to a different production run with different parts. Then check the part number printed or stamped on the part you are replacing against the part numbers in the table above; the printed number is the most reliable way to confirm fitment when a model has gone through multiple production runs. RepairKitHub does not sell parts directly — every part link above routes to an Amazon search for that part number so you can compare current listings and sellers yourself.
How to confirm this is your model
On most dryers, the model and serial plate sits inside the door opening or behind the lint trap. Match every character exactly, including letters and dashes at the end — appliance model numbers often have similar prefixes but different suffixes for different production runs.
