Reasons Why Your Husky Air Compressor Won’t Start

The main reasons as to why your Husky air compressor hums but won’t start are likely to be due to any of the following reasons summarized in the table below:

Potential IssueTip
Power issueAvoid using power bars and power strips.
Fuse or breaker blowsCircuit breakers will trip off when a power surge blows their fuses. If the fuses are faulty, you will need fuse replacements.
Faulty pressure switchUnplug the Husky compressor from the electrical outlet before opening the drain valve releasing the air from the tank down to zero and then closing the drain. 
Faulty thermal overload switchCheck the thermal overload switch to ensure it is working correctly.
Faulty unloader valveCheck unloader valve, if faulty pressure switch may not work.
Insufficient oilCheck the oil level, and inspect under the pump area for any potential leaks.

I just used it the other day with no issues I tried to use it last night to turn the switch and nothing happened . checked the breaker it’s fine, checked the reset button on the motor that was fine, pulled the cover off the compressor switch saw everything connected and that looked to be fine what should be my next step or what do I need to do to fix this issue


Husky Air Compressor Won’t Turn On

Up until a couple of days ago, the compressor worked fine but I noticed that lately it only charged to about 60psi. Then it would not restart after being off for about a day. Light usage through the years (about 10 years old)?

Diagnostics I Tried:

1. Tank drained to zero, even pulled the over-pressure plug.

2. Disconnected motor wires from the switch and wired them directly to AC. Nothing. Does not make any noise or even indicate that it is getting power. This means that the pressure switch is not the problem.

3. Read about capacitors on your site but could not find any (picture attached). Wires seem to go right into windings. The black cover does not look like it comes off easy (snap-on bottom is obscured). However, another post says that if caps are fried then it will not start and you will need to pull the motor. Ugh.

4. Checked ohms on motor leads (that is what you see in the picture). It reads as 1 on the meter, meaning it is an open circuit … as if the motor was not even attached. I sorted the leads to the motor, nothing so no cap charge waiting to surprise me.

5. Motor rotates freely (some resistance) by hand. Linkages all seem to work, fans are in good shape. Hesitant to try to remove motor because copper pipe on the bottom is shaped for a specific position and that would be a pain to replace.

6. Saw CHPower.com reference and phone of 800-543-6400 if you all think I need to replace the motor.
