Question about Magic Chef Refrigerators

Open Question

Magic Chef Model: mcwbc77dzc Not cooling. Need help identifying a part.

After a recent power outage my beverage center will no longer cool. I have verified the following: Compressor is coming on and measured ok. Compressor fan is on. Cooling fins are free of dust Temp sensor is working measured resistance. I hear 3 clicks when I first plug in the cooler. These clicks are not coming from the compressor start relay. They are coming from a different relay that has 2 wires going to it directly connected to the main PCB. There is a brass line the is routed through it. I am assuming this is some sort of pressure valve that allows Freon to flow. Does anyone know the official name of this and where I can find one?

This sounds like the thermostat is the problem. I wouldsuggest touching the compressor at the back of the unit to see if it is hot or cold. If it is hot then you have probably have power down to the compressor, if it is cold you could (if capable) bypass the thermostat to see if it kicks in. Hope this helps.

SOURCE: Cooling fan wont work

The water temp sensor is located near the thermostat housing. This sensor is what tells the ECM to turn the fan on/off. The water temp sending unit is located near the same area. You know you have the correct sensor is because the water temp sensor has a 2 prong plug. The water temp sending unit only has 1 prong.

SOURCE: Maytag refrigerator isn't cooling

Hi ****, Based on the discription you've provided it sounds like either a faulty start relay or the compressor is seized. If you have a multi- meter you can check the compressor to see if the windings are ok. Unplug the fridge. Remove the panel at the back down at the bottom. This should gain you access to the compressor. On the side of the comp. will be the start relay/overload assembly. Pull off the relay & overload and you'll see 3 pins in the form of a triangle. With a meter measure between any 2 pins at one time, going between each pin with one remaining on a "common" pin. You'll want 3 measurement's, similar to this example- 6ohms, 3ohms, and 9ohms. On some meters you may simply get a reading of "0" ohms, as long as the needle moves off of "infinity" which would indicate an "open" winding=not good ! If following that, the readings are good, purchase a hard start kit. Part # HS410 also known as a 3in1 starter kit. This will start it if it's not seized also known as a "locked rotor".. You can find them at most brick & mortar appliance parts locations or on-line vendors. The package contains info on how to connect it. If that doesn't yield any results moving forward, let me know we'll go from there. **I suggest you phone Whirlpool customer support first though ( they own Maytag ) as they recently had a massive recall regarding the starting device of many compressor's and you may find your's to be included therefore have it repaired at no cost.** they will know by your model and serial number or if that isn't clear the number on the compressor. Good Luck Thanks for visiting "fixya", please take a second to rate my solution and leave a comment/testimony to it's helpfulness. macmarkus :)

I have a beverage air MM14GE cooler that hasnt been on for over a year when i plug it in it turns on but doesnt cool, what can be the problem?

Verify that the compressor is actually running. You should feel it vibrating. If the compressor runs with no cooling most likely the refrigerant level is low.

Not cooling

You can ohm the compressor to see if it is shorted but if the compressor is running it cannot be the overload or relay , if not running sometimes you can pull the relay and shake it if you hear any rattling in it it is bad

Refrigerator overload protector intermittent

To be short, the only thing in the machine that really has the capability of causing that is the compressor. Its got a floating short in and when it makes contact it trips the outlet/breaker. Check for any exposed wires just to be sure but I'm pretty certain that the compressor is the culprit and either it or the machine needs to be replaced or a proffesional sercvice tech called.

Should we replace switch.

Many times the oils in the fan motors gum up and solidify after an extended shut down. Check that the fans are running. It's doubtful that in this case the switch is at fault.

What does the overload relay look like a Beverage-Air MT27 Beverage Cooler Commercial

Normally thermal overloads have a button like appearance on the compressor. Designed to open circuit when temp has caused distortion to the bi-metal contacts. Upon cooling will close again. Disconnect power before checking continunity on the overload terminals.

You have to verify that the compressor is running. Don't assume that it is just because the fan is running. the compressor may not be running. If compressor is running, good possibility that it is low on refrigerant. Most common and obvious.

No longer cools.

This refrigeration system may be under extended warranty.
Otherwise check the compressor start relay for loose or burned contacts.

GE Monogram Bev Center no longer cooling

Depend how old it is, Monogram does have a better warranty then regular appliances, sounds like it may have a bad power supply board in the back. It may have a compressor problem but the circut board  is more likely. It would probably be worth  having a GE tech to come and give you an estimate a the very least. Only because if you purchase the new board and install it, most places will not accept returns on electronic parts. Hope this helped.

electrician do one thing, electricity. If the unit cools, the compressor is running. a power outage should not put the compressor in a "Weaken" state. I would check the starting components. don't overlook your surge protector causing a voltage drop. try running the unit without the protector.
let me know if I can be of any further help.
