Hello, Many people have had problems with their refrigerator compressors not starting and wonder what may be the problem. Many times the problem can be traced to the start components. The start relay and the start capacitor work together to help the compressor get started. By giving it a short extra shot of higher voltage current, it gives the compressor the kick to get it turning up to speed.

The capacitor is the long round tube on the top of the box that houses the compressor terminals and the start relay.

The start relay is pushed right onto the compressor terminals C and R. It also has two wires that go up to the start capacitor.

The relay can be removed by just pulling out on it away from the compressor off of thecompressor restart procedure - 10dc905.jpg>

If your refrigerator compressor is not starting, you can change the start components easily, to see if they are the problem. Usually you will have about a 50-50 chance of the compressor wcompressor restart procedure - 392b551.jpgn by changing these parts.

Campbell Hausfeld workhorse 3.5 stops after it gets hot and only hums when you try to restart. After sometime left turned off will restart but does the same thing

This fault indicates that there is too much back pressure on the pump causing the motor to strain. There is a check valve located at the tank that prevents pressurized air from returning to the compressor. Here is how to test for leaking check valve. With no air in the tank, run the compressor till you reach about 40psi and shut off the unit. Listen or air leaking out of the air filter or the pressure switch. Leaking air indicates bad check valve. If no leak, allow the compressor to reach fail condition, then unplug the compressor and immediately let out all the air and see if the compressor restarts easily. If the compressor will not restart with no air in the tank then may have failing capacitor (s). Easy to replace. ;Good luck with your repair.

Duo Therm A/C (2009 Sabre RV) won't shut off

bad compressor relay on control board. The relay is not opening the circuit, allowing the compressor to stay running when unit is turned off. This overheats the compressor and opens a thermal disk shutting the compressor off. When thermal disk cools down, the compressor restarts under load and trips breaker.

[email protected] fridg& frezer will chang 30 to 40 degrees if you open either door it will take a long time for for temp to drop

The compressor is the part which cools the refrigerator.---------- First i will explain the working procedure of your sanyo refrigerator.---------- In the refrigerator, there is a part called compressor, the compressor is the part which cools the freezer section, When the freezer reaches its cooling level the defrost cycle starts functioning. In this cycle the fan in the freezer section starts running and the cool air in the freezer section is passed to the fridge section and the fridge section gets cold.--------- So the freezer section cooling/ freezing is must.If freezer is not getting properly cooled or not getting cooled, then fridge section will show the low or no cooling problem.--------------
In your refrigerator, its quite possible that compressor is got weak, nor complete faulty but little bit weak.So when you open and close the fridge or freezer door , the compressor is not that strong to maintain the required temperature.So its working hard to cool inside temperature, but its not doing it quickly as it should.---------.---------- In the compressor there is a refrigerant called FREON.With the help of this Freon the compressor cools the freezer section.Freon is a gaseous type cooling agent.The compressor will stop cooling when coolant gets leaked from its chamber.--------- Again recharging the Freon is possible, but the cost for that recharging is approx the cost of new compressor.So its always advisable to get compressor replaced.Because new compressor has warranty for few years.------------------ You can get required parts from from online sites like: --- www.repairclinic.com or from searspartsdirect online site. --------- ----------------
There is manual reset procedure, sometimes the ice gets frosted all over and blocks the ventilation's for cool air to pass from one section to another, and this also causes problem.So directly going for compressor inspection, before that you can try manual reset procedure and see if that helps.---------

The manual reset procedure is as follows : ----
First unplug the unit from main power outlet. Then empty whole unit completely. Then keep both the doors open. Wait for 24 hours. All the ice collected on the coils and in the freezer section will get melted. Clean the water from the sections. Then Connect the power cord of the unit to main power outlet after 24 hours/.Then set the temperature to normal in both fridge and freezer section. It will take approx 4 to 6 hours for your refrigerator to regain its regular cooling/ freezing .So after 4 to 6 hours check , Is the refrigerator cooling properly or is it taking time or temp is dropping once you open close door. If this problems are not noticed, then reset procedure has helped.------- But if same problem is noticed after reset procedure is followed, then you can get the compressor checked. -------- This should help. Thanks.Helpmech.

Freezer and refridgerator not cooling. Clicking sound comes on every 4 6 minutes.

Hi and welcome to FixYa, I am Kelly. The clicking your hearing is the compressor thermal overload cycling. If there was a momentary power loss the internal coolant system pressure will be to high and the comprssor will not start. The additional heat generated from the continued thermal overload cycling is enough to keep the compressor from starting after a power loss also. Unplug the unit for about 20 minutes and then pluch it back in. Hopefully at this point it will start. If not there can be a few things that will cause it not to start.

1. The comprssor PTC Relay mounted on the side of the compressor under the plastic cover.
2. The black run capacitor usually located on the chassis to the left of the comperssor.
3. The compressor rotor has locked due to an internal failure or a compressor winding has failed.

If after the 20 minute power off period it does not restart please respond with your complete model number so I can make reference to parts and troubleshooting procedures with a Meter / Tester.

Thanks for choosing FixYa,
Kelly

Locks up on restart untill the pressure. is down around 50 lbs.and kicks out the breaker

The pressure bleed valve is not working when the compressor shuts off. It is supposed to drain pressure from the compressor air line to the check valve and pressure regulator switch so that the compressor restarts with low pressure in the output line.

Refrigerator starts -runs for two weeks, compressor won't restart

It might be but I would first check the condenser to see if it's blocked or if the condenser fan (if it has one) is not working. The "buzzing/humming/ticking" sounds you're hearing is the compressor trying to restart after it became locked down. Excessive pressures in the system or compressor overheating is usually the cause although sometimes the bearings in the compressor simply lock up.
Check to see if the fridge cycles on and off by the thermostat. If it doesn't cycle and just keeps running then the thermostat is bad and that can cause compressor failure thanks to "slugging". If it does then you want to check the defrost timer. Turn the timer's dial until it clicks into defrost and see if it comes out on its own. Check if the compressor has trouble starting after defrost. If it stays in defrost the timer is shot. If the timer times out and the compressor will not restart then the relay might be bad or, the compressor might be going bad.
A 3in1 relay/capacitor/overload might help out and give the unit a little longer time but sooner or later it will go.

Porter cable compressor will not restart once it is under pressur

This is likely a bad check valve which is allowing pressure from the tank to leak thru back to the compressor. The compressor won't start because the compressor cylinder has air pressure on it.

The check valve is about the size and shape of a .410 shotgun shell -- it's in the copper line from the compressor to the tank.
