Customer Questions and Answers for Timer (Fm-3) by Whirlpool

This mechanical cycle timer controls the sequence and duration of operations in your appliance. Replacing a worn timer restores proper cycle advancement so the machine starts, progresses, and shuts off at the correct times.

• Advances the cycle by opening/closing internal contacts at set intervals
• Coordinates stages such as start, run, and end-of-cycle depending on model
• Common failure signs: won't advance through the cycle, stops mid-cycle, runs too long/short, or won't start/stop
• Helps correct intermittent or inconsistent cycle timing

• Disconnect power before service; allow any moving parts to stop completely
• Access timer from the control console; note wire positions before removal
• Transfer any mounting clips/brackets from the old unit if present; align shaft with knob
• After reassembly, run a test cycle to ensure proper advancement
