Fans & ventilation
Ceiling fans, exhaust fans, speed and noise faults.
Ceiling fan not working
A ceiling fan won't run (light may still work, or not) — pointing at the wall control/remote, the capacitor, the motor, or the supply.
Ceiling fan noisy, wobbling, or running slow
A ceiling fan runs but wobbles, clicks/hums, or only runs slowly — usually balance/mounting, a tired capacitor, or controller issues.
Bathroom/laundry exhaust fan not working
An exhaust fan won't run, runs weakly, or keeps running — common causes are the switch/timer, a seized/dusty motor, or supply.
Fan only runs on one speed or wrong speed
A multi-speed fan is stuck on one speed, or the speeds don't match the control — usually the speed controller, capacitor, or wiring.
Bathroom 3-in-1 (heat lamp / fan / light) not working
An IXL Tastic-style 3-in-1 bathroom unit has lost one or more functions — heat lamps dead, fan not running, light out, or the whole unit lifeless. Which functions are dead tells you where to look.
