Low voltage at compressor!

Getting low voltage at compressor, meter only reads 15 volts at relay, condenser fan runs and evap fan runs,  why are fans get proper voltage and not compressor!!  I am getting proper voltage  going into wire harness but not coming back to compressor!!  checked relay and overload and start cap, all good,  checked compressor with annie, compressor is good, I am just not getting proper voltage to compressor,any idea's   I am stumped,  I do light commercial refrigeration and some household  refrigerators, never had this problem before!!  I do not have wiring diagram to check!!

Re: low voltage at compressor!

My parts lookup too has no images available for you refrig but i believe it to be a GE Profile with a fresh food fan (and air duct down the center of the fresh food side). All fan motors are 12vdc and run off the Lowvoltage side of motherboard. i assume you are checking voltage to comp from motherboard? How did you check relay?? Have you axcessed motherboard?? On the top of (I say top-- i belive its mounted horiz on yours but all the small wires are on the right) is all the low voltage fan motor, damper, control wiring On the bottom (or the left) side of the motherboard is the larger line voltage wiring. The connector with 3 wires is labeled def -- comp---line it should be blue. Try jumping L1 to comp. ((Just so ya know Def will energize the def heater regardless of compartment temp it does have a bimetal but it only a safety set at 100deg in case relay on board welds shut---it monitor evap compartment, frz, fresh food, (two seperate in FF) in your model))

Why would evap fan running slow

If u turn the fan by hand and it turn then u need a new fan, and i think u are mixing up the fans, the fan inside the refrigerator would be the evaporator fan if that was broken then your compressor would be cold, the fan inside the compressor section would be the condenser fan, if that was defective then your compressor would be hot causing the compressor to short cycle. change the fan and clean your condenser coil and your problem should be gone,

All compressors have a 1) Bi-metal t-stat and Most have 

2) Start-Capacitor assist with 3) Plug-in Start Relay.

 All 3 parts are available at Most Appliance Repair stores and are not that expensive. It is usually 1 of the 3 that has failed.

If your Condenser Fan is Running it is one of the three components or a burnt off wire ... Be Safe.


Good Luck.

Refrigerator running but not cooling

Is the fan running in the back compressor area?If not check voltage at the fan if there replace fan motor.[Condenser motor] Is the fan running in the frezer compartment if not check for voltage at that motor if voltage there replace motor[Evap motor]
Is their frost on the frezer back wall,in side the frezer compartment? if yes its a defrost problem.Use volt meter to check continuty on heater and term.thermostat [It must becold below 20 degrees to check term thermo.if those 2 ok its defrost timer

Refrigerator wont get cold

If compressor is running check and make sure your cond. fan and evap fan are running. Also check in freezer and make sure evap. coil is not covered in ice. Also clean your condenser coil. You could be low on refrigerant. There are quite a few things to check.

No cooling in fridge or freezer. Unit has power - light goes on.

Hi greenhouse76,

Please check if the compressor is running. If it is running and the machine is not blowing cold air inside the freezer. You may have either a restriction inside the sealed system or have a leak in the sealed system and all the Freon has escaped. No Freon, No Cool. Not a DIY job.

In order for the machine to get cold at all, the motor has to run. If the condenser fan (fan by the compressor) is running and the compressor is not running then you have one of a few problems. Either the motor is not getting power and that's why its not running, or its getting power and the windings inside are shot and that's why it's not coming on.

When the condenser fan is running you need to check to see if voltage is getting to the relays on the side of the Comp. More often then not, these are the parts that go bad. First Check for voltage to the relays and see it they have 120 Volts AC. If so, check the pins on the compressor that the relays connect to. From this point you are going to need to remove Compressor Relay Cover the clip that holds the relay to the side of the compressor, then unplug them from it and take them off.

Hope it helps.

Thank you for using FixYa.

This is what to do. On the side of the compressor is a relay overload set. Unplug the power cord. Connect a meter to the wires going into that set. If there is no power you will need the mother board linked below. If there is power you will need another overload relay set.

Panel between doors is very hot-compressor is hot. With compressor running fan is not. There is 32V AC at the fan connection, but the fan says it is a 115VAC

Good day,
First step. Unplug the machine. Your ruining the compressor. If your model has a 115 volt ac condenser motor then that is the only voltage it will run on. If this has been going on for a while, good chance the condenser fan motor is terminal, if not near so.

The first thing is to find the complete model number, style and age of the machine. Could be the motor is controlled by a circuit board, but without that this is as far as we can go.
P.S. Check you meter in a wall socket, to verify it is reading properly.

My refrigertors stop working

First thing to do,is,see if the compressor is running,it should be humming,and warm to the touch.There should be a fan running under the unit,cooling the condenser.And the fan in the freezer unit should be running.If none of these are running,check to see if there is current in the wall plug,maybe plug it up to a known hot,receptacle.If the fan in the freezer is working,or the condenser fan,check the thermostat to see if it is working.If it is,take a 120 volt,volt meter,and check the voltage going in the compressor,if it is getting voltage,and is real hot to touch,then it is bad,the compressor,or if it s not running,then it is bad.If the compressor is running,and the large line off the compressor is cold,or near it,then it may be just low on freon.So many things to check here.

Compressor in fridge not working. Freezer is working fine. Is there a reset button? What steps can I take to see if this is a simple issue?

There is one compressor that serves both the freezer and refridgerator compartments. You need to confirm if the evaporator fan in the freezer compartment is working. When you open the door to the freezer, you should see and hear the evaporator fan in the freezer compartment running. Particularly if there is a demand on the unit through the thermostat setting. If the evaporator fan is not operating, you can check the evaporator fan motor with a volt meter to see if it's getting power. If its getting voltage, but not operating, you need to replace the evaporator fan motor in the freezer compartment. There are 3 wires that attach to the evaporator fan motor. One hot wire, one neutral wire and one ground wire. The ground wire is usually marked green, the voltage wire is usually marked black and the common wire is usually marked white. You should get a reading on your volt meter of a voltage from the hot post to the neutral or from the hot to the ground. If it is getting power but will not operate, then it is definitely a bad fan motor that would need to be replaced.

GE Refrigerator Compressor Inop.

I found this post by searching on the capacitor number, JSU21X126AQC. My 2001 Kenmore refrigerator (don't have model# here) compressor didn't run, but I heard it hum for a few seconds and then a click. That's the Klixon overload doing its job. I measured resistance of the compressor leads same as original poster. This lead me to determine that the windings were not open or shorted. The wiring to the compressor also fed the condenser fan, and it was running, so power was at least all the way to the compressor.
What I did find was that the 12uF capacitor was only 4uF. My digital volt meter has a capacitor check range. This compressor circuit is a permanent split capacitor type. Without the proper capacitance, the compressor can't start. I replaced it with a 10uF, 220v AC capacitor I had, and now it runs fine. I wonder how many refrigerators are scrapped because of this inexpensive problem?
