Williams 4007332 Fan Capacitor
The capacitor is designed to control the speed of the fan of the wall unit. Some wall units help by making a replacement easy to do, while some design it to be difficult at best.
Signs to watch for in a bad blower capacitor
- The fan capacitor looks terrible and smells burnt as it sits inside the unit
- Only sometimes turn up or down the rate adjuster for the main blower
