What causes a delay in the start up of my air compressor?
If your outside unit isnt cycling on and you have line voltage coming in to L1 and L2 first thing I would check is the contactor you say it does come on.If its cooling when it comes on the your condensor fan and compressor are working fine. Likely a relay timed to close (tc) and create a delay.
Why does a compressor take 5 minutes to restart?
Also, compressors in heat-pumps have a five minute time delay to protect the compressor from high pressure due to switching from heat to cool or vice versa. The 5 minute time delay in this case protects the compressor from high pressure caused by the change in the flow of refrigerant at the reversing valve.
What happens when the unloader valve on an air compressor fails?
When the unloader valve fails, however, air will be trapped over the piston or pistons on the air compressor. That adds load to the drive train. Smaller air compressors operate with a very thin line between motor size and the power needed to drive the compressor pump.
Why does my air compressor not turn on?
The lights in the house – at least those on the same circuit – may dim as the compressor motor tries to start. If the motor tries to start for long enough and still cannot get going, the motor will overheat and shut down on a thermal cut out switch, if it comes equipped with one. Test the unloader. How?

Why do refrigerant compressors take so long to restart?
The real reason refrigerant compressors have a delay before restarting: consumers are cheap. We demand lower cost so manufacturers omit useful but optional parts that would increase equipment lifespan and they downsize other parts to reduce the build cost.

What happens if your air compressor overheats?
If the motor overheats, the thermal cut out will shut it down. If you are using your air compressor for extended periods, more than, say, ten or fifteen minutes at a time, the typicaly DIY air compressor will overheat. The duty cycle of the compressor may be less than the time you are requiring it to run, and the motor will overheat.

How to fix problems with an air compressor?
1 Restricted air intake. Clean or replace air filter. 2 Oil leaks. Tighten bolts or replace gasket. 3 Worn piston rings. Replace rings. 4 Wrong oil viscosity. Drain oil, refill with oil of proper viscosity. 5 Compressor tilted too much. Level compressor. 6 Scored cylinder.
What happens when an air conditioner compressor stops?
if an air conditioner compressor stops, it still has pressure built up inside. This pressure prevents the compressor from easily starting. There is a safety switch that won’t allow the compressor to start until the pressure bleeds off. If the compressor tried start with pressure in it, the unit is essentially “locked up” and would blow the fuse.

The 5 minute time delay in this case protects the compressor from high pressure caused by the change in the flow of refrigerant at the reversing valve.
Why does the reset button on my air compressor always trip?
If the compressor reset button always trips on your compressor, the motor is getting too hot! Check to make sure that your air compressor is plugged right into the wall socket, and it is not being powered through an extension cord or power bar.
