I have replaced a compressor in a maytag fridge model MBB2256GES and i have a blue wire and a white wire i know they go to the compressor and ther are three pins on the compressor what goes where

Jason, your solution was PERFECT! I got the switch and installed it and the fridge is humming along better than ever. I had read horror stories about the Tecumseh compressor and figured I was looking at having to get a new compressor or fridge. $60 for the switch and I'm in business. Thanks very much!

If the model number is correct and you replaced the=>12555902 Start Relay with Overload along with the-> 65889-4 Run Capacitor
and still having trouble the compressor may be defective due to binding because of wear, age, factory defect or you are trying to restart too soon after the compressor last stopped. No promises of a fix but the=> URCO810_Supco_Start_Relay_3_n_1


may be useful in a worn binding hard start compressor but may last a good long while Sea Breeze

Sounds like one or more of ofvyour 3 defrost components have failed which are defrost heater , defrost thermostat, and defrost timer or board

yes as it is the ground wire to prevent electrocution

Good day,
You have to remove the rear panel in the freezer compartment. The thermostat is clipped to the top of the cooling coil. Fairly simple job.
Here is a picture of one style..

Good day,
You access it from the front removing the rear panel in the freezer compartment.

Note: the heater may have failed, but has a very low failure rate.
If the machine is not defrosting, the timer and defrost thermostat ( sometimes called a limiter) are just as if not more often the problem.

12 o'clock red...4 o'clock blue...3 o'clock white .( the white , has the smaller terminal )

If you had to lay the fridge down to move it? Then you have to let it stand upright for at least 24 hours before you can plug it in and use it or it won't cool, as oil will get into the coolant lines and foul the works.
If you didn't have to lay it down, then check for a switch and or harness under the front grill that may have got bumped out of adjustment of knocked the plug off.
I hope this helps you, and good luck.

you must change out the relay to find out if the compressor is locked , but before this is done let the compressor cool to room temp. then try again.

depending on model thats either your timer or cold control would be about 200
