Controls, timers and wiring
Symptom: A cycle that doesn't advance, an unresponsive display, or the unit not starting at all.
Check: Look for burn marks or a burnt smell near the board or terminals, and check whether buttons and knobs respond -- a unit that powers on but won't cycle often traces back to this group.
Parts in this group on 31AM63LF704: 72504314 (Snowblower Wire Harness), 72504622 (Snowblower Wire Harness).
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.

Before you buy
Match 31AM63LF704 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
Check inside a door opening, on a back or side panel, or behind a removable panel or drawer for a label printed with the model and serial number. 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.
