Why does my Craftsman air compressor keeps tripping breaker?
If the capacitor is weak or failing, the boost isn’t there for the motor, it tries to start, pulls too many amps for the circuit, and your breaker trips out after a couple of seconds.
Why did my Craftsman air compressor quit working?
Look for blown fuses or tripped circuit breakers at the home’s main power panel. Reset any breakers and replace fuses. Check for the proper fuse. A simple, portable two-gallon air compressor needs a 5 amp, 250 volt fuse.
How does the air compressor start and stop automatically?
The air reservoir has pressure switch which is set for cut-off and cut-in depending on the pressure desired. When the pressure drops below the cut-in setting, the switch energises the contactor coil and the compressor starts.
Why does my air compressor keep cycling on and off?
Short cycling, when the compressor constantly shuts on and off, is one of the most common air conditioning problems. Several conditions cause short cycling, including a faulty or obstructed thermostat, leaking refrigerant, icy coils or an HVAC system that is too big for the building in which it is installed.
How do I stop my air compressor from tripping the breaker?
Turn off or unplug the compressor. Drain the compressor tank and then close the drain. With due regard to the presence of live terminals inside the pressure switch, pull the cover off, reset the breaker, and watch inside the pressure switch to see if there is any arcing or sparking when you turn the compressor back on.
Why is my AC compressor tripping the breaker?
Typically, your AC breaker trips when there’s a short circuit, the AC is overworking or a part is bad or malfunctioning. If you continue to run your AC, you could permanently damage the air conditioner. Get a professional AC repair tech out as soon as you can.
Why does my Craftsman air compressor not start?
It’s common and normal for a Craftsman air compressor not to start. The motor won’t run if the tank pressure exceeds the preset pressure switch limit. The motor starts automatically when the tank pressure drops below the kick-in pressure of the pressure tank. This is to prevent the tank from exploding.
How often should I drain my Craftsman air compressor?
Pull on it and look for obstructions. Drain the Craftsman air compressor tank daily and operate the pressure relief valve daily. Moisture is a byproduct of pressure and will damage the tank. The pressure relief valve can stick through debris collection and is an important safety feature. Patrick Nelson has been a professional writer since 1992.
When does the air compressor start to work?
The motor starts automatically when the tank pressure drops below the kick-in pressure of the pressure tank. This is to prevent the tank from exploding. There is no need for the air compressor to create pressure until you have released some pressure.
Why is the start capacitor on my air compressor not working?
The start capacitor cover on your compressor motor may look the same as the one shown in the photo, or might differ slightly. As we have been trying to find out why our Craftsman air compressor will not start, in previous pages we’ve traced the power supply successfully to the motor circuit.
