Why would a whole house fan only work on 1 speed?
A whole house fan that only works on one speed may have a faulty motor or a damaged speed control switch. It could also be a problem with the wiring or the fan's internal components. It would be best to have a professional electrician or HVAC technician inspect and repair the fan to ensure it operates correctly and safely.
What causes a ceiling fan to go from three working speeds to only one?
A common reason for a ceiling fan losing speed settings is a faulty capacitor or speed control switch. The capacitor helps control the fan's speed settings, and if it malfunctions, the fan may get stuck on one speed. Similarly, a faulty speed control switch can limit the fan to only one speed setting. Both issues would require repair or replacement by a professional electrician.

Why does a fan only work on high?
More information would be needed to diagnose your problem more accurately, but here are some tips to start: 1) Fans will not work with dimmers. If you have a dimmer controlling your fan, it will only work when the dimmer in is the full intensity position (if at all). You will need to replace the dimmer with a fan speed control. If one switch controls both the fan and the light, this will not solve your problem, as a light will not work with a fan speed control switch. You will have to settle with a standard single pole switch, a remote switch, or get one more wire between the switch and the fan. 2) If you have a fan speed control switch, but the fan doesn't seem to respond as it should, you may want to pull on the pullchain directly on the fan. If the pullchain is not set to high, your speed control will not work correctly. 3) If #2 or #3 don't apply to you, and you are simply using the pull chain on the fan, you may have a bad switch inside the fan housing, loose or disconnected wires to the fan (unlikely), or simply a bad fan motor.
