If you are only getting to 45 psi, you have a problem with either your reed valves or piston rings/cylinder assembly. If you feel comfortable taking it apart, removing the head(s) on the pump will let you inspect both to see which is the problem. The reeds on the valve plate have to be in perfect condition. Buildup, broken or bent reeds will prevent them from sealing so air can be pumped into the tanks. If the seal (oiless) or rings (oil lubricated) around the piston are damaged the same result will occur. These can be indicated by excessive wear marks on the cylinder or stray peices on top of the piston. Both are simple fixes and fairly inexpensive. Without your model number I don't know which parts to recommend. On Ridgid's website they have an excellent parts lookup system and you can order from them or use the part numbers to check other websites for prices.

Compressor relay switch


What temperature is this heat pump being run at? If it is low ambient temp outside this may be running in what is called defrost mode to where the compressor will run without a call for heat. This seems normal to me as long as the setpoint temperature is being reached.

Freezer motor will not turn on


Try cleaning the unit out and any coils you can reach (typically located near the bottom of the unit behind the toe grille). Do you hear the compressor running? The compressor is constantly meant to go on and off frequently to keep unit at a constant temperature. If you do not, the unit could possibly have a coolant leak or an issue with the internal sealed system including a faulty compressor, evaporate fan or main control board. Contact a professional move forward accurately.

You can but the unit will have not control over temperature, and you can cause the unit to freeze up or slug the compressor w/ liquid refrigerant causing premature compressor failure. I would recommend replacing the thermostat if it is not holding proper temperature, but if dead set on bypassing it use a volt/ohm meter after unplugging it to find the normally open contacts and wire those wires together taking into consideration that the fan must run constantly with the compressor.

Unit will not stay cool. Is it a thermostat, compressor?


Small refrigeration units like this one like to fail to cool by developing a small leak and slowly
leaking refrigerant.
THERMOSTAT FAILURE CHECK:
A technician will check the thermostat using using a DMM (digital multimeter). But you can suspect the thermostat if you set the thermostat high and the compressor motor does not run,
then set thermostat low, and the compressor motor also doesn't run - in other words, the thermostat is failing to start the refrigerator's refrigeration system no matter what its setting - an obvious failure of the thermostat.
COMPRESSOR FAILURE CHECK:
If the compressor is dying, you would hear the compressor running almost constantly, but not
sounding quite right (uneven noise, clunking, tapping).
REFRIGERANT LEAK CHECK:
If you unit is low on refrigerant (due to a leak), the compressor motor will be running
almost constantly, but it will sound Ok.

The air ride stop working


There are a few things that happen most often on these vehicles. Air suspension compressor failure,A/S relay and a small coupler under the master cyl breaks. Listen to see if the compressor runs if it does check the air line coupler under the M/C to see if its broken,if not it,its possible the compressor motor is ok but the cylinder is worn and not producing pressure,you can check this by removing the air line on the compressor and checking the airflow out of the line(it should be significant). If it is it could have a leaking air bag also

I have worked on many makita compressors and have run-across this problem on a few of them. Your compressor has a check valve that is supposed to hold tank pressure after the switch reaches set pressure. There is an unloader valve built into the pressure switch that releases the pressure in the discharge hose after the unit shuts off. The unloader allows the compressor to restart with-out any pressure in the discharge line. If the brass check valve is leaking pressure back into the system, air will leak out of the unloader valve. Follow the discharge line to the tank and you will see the brass check valve. To test valve for fault, run the compressor till it builds around 80 psi and unplug the unit from the wall outlet. Remove the 1/4" hose connector from the check valve and check for air leaking out of the valve. If it is leaking you can order form www.toolpartsdirect.com. or call the makita 1-800 number. The price is about the same. Good Luck on your repair.

Hissing sound and constantly running generator


The only thing I can think of that you may be hearing would be if the compressor has a problem. If you notice cooling performance decrease or it stops cooling, I believe you will find the compressor has bad internal valves. It will probably take a technician to properly diagnose this and if the compressor has this problem the only answer is to replace the compressor.
I hope this helps, supertechks
