I have a Whirlpool Mark Series that quit cooling. Checked for power to the compressor and there was none. I decided to "hotwire" the compressor to eliminate any switches or wiring. The compressor still would not start so I tried a start capacitor that had values that were close to the original. The compressor (~2.5 amps) will now run and cool . The condensor fan does not have power to it, but the evaporator fan runs . If I unplug the defrost timer, the evaporator fan will not run. I have checked the thermostatic switch and it has power to it and it has continuity. The red wire that plugs into the juction block (by the water valve) does not have power at that location. It appears that the red wire is broken between the thermostat and the junction block . It anyone has a wiring diagram for the unit, I would very much appreciate it. The fridge has been running for about 3 hours with fans blowing on the condensor coils and the freezer temp is down to 6 deg. F.

I cannot find any info on a RNR4 but there are parts for a RWR4 see below.

Also I cannot find a wiring diagram for either a RNR4 or a RWR4 but I was able to get one for a RWR3. It is probably very close or may be an exact match to your unit.
See the attachment.

It also has a wiring layout which should be a big help tracking down the open in the circuit.

Denman,
Thank you for the wiring schematic. I ran a jumper wire from the condensor motor to the terminal block, hooked up the compressor wiring as it can from the factory and everthing works. The schematic shows a "connector" between the terminal block and the evaporator motor. The "connector" is not accessible from the inside or outside. I am guessing the connector was damaged from the high amps that the compressor was pulling (~25 amps)after the start capacitor failed. I guess I get a new fridge for Fathers Day.

You seem to know what you are doing so why not jiggery pokery a wire.

I would take it off the main thermostat and just drill a hole out the back of the fridge. If you hit a freon line there is no loss as you are going to scrap it anyway.

Denman,
Went and looked at fridges and no one had one in stock that the me or the wife was interested in. I drilled a hole thru the back wall and ran a wire from the evap. motor to the terminal block by the water valve. I ran the wire thru a rubber hose to protect it fron the sharp edges. At least it will buy me some time to get one we want. I hate all of the new electronics they have on them and the high dollar water filters that you have to buy. I will do an autopsy on the old fridge when I get a new one, to find out were the wire lost connection. Thanks again.
