HOW DO YOU PUT UNIT INTO DEFROST MODEL GSSS23SGSA SS. IT HAS A PCB CONTROL ?



b378fef3-2cc4-418b-b21c-b964c1bd449f.jpg
The GSS23SGSASS Refrigerator uses the motherboard to cycle the defrost heater but jumping the L1 to the J9 terminal will cause the defrost heater to come on while a jumper is in place. If unsure please let someone that has worked with electricity perform this step. A diagram can be found=> HERE and a Service Manual HERE The most liely problem is a burned out=> WR51X10101 Defrost Heater Assembly It is a good idea to also change the=> WR50X10068 Defrost Thermostat while inside the freezer evaporator compartment changing the Defrost Heater.

How to test electric derost heater coil for maytage refrigerator model #msd2656dew


Hello,

To test that defrost heater...unplug it so its isolated from the rest of the wire harness and their will be 2 wires on it...use a multimeter set to a low ohms setting and place one meter lead on each of the wires and the meter will dispaly appx. 10 to 20 ohms if the heater is good and the meter display will not change if the heater is broken.

If you find the defrost heater to be good the next thing to check is going to be the defrost thermostat...to check it, it must be cold so check it when thier is frost built up on the freezer coil also isolate the wires from it and use the meter and check for ZERO ohms WHEN ITS COLD if zero ohms its cold and if the meter display doesnt change it will be bad

If both the defrost heater and defrost thermostat check to be good the defrost control board is going to be the problem

this is what the defrost t-stat looks likeoldtech2332_99.jpg

Think we need to install a heater since freezing up - model # csx22gr - where is heater, evaporator, and how do you change it out?


Defrost heater is attached to evaporator behind the cover plate in the freezer. Change out the defrost thermostat while you in there (the defrost thermostats are inexpensive , so if yo are putting a new heater in it makes sense to do the t stat also.
Just wire the new components in the way the old ones are. I would check the defrost timer first before assuming the heater is bad

Refrigerator not defrosting


Normally, the defrost heater can be checked for continuity rather than ohms of resistance. If the heater is o.k., then your problem may be the defrost thermostat or defrost timer. Contact an appliance service company.

The next step would be to unplug the refrigerator and remove the rear panel and defrost so that you can unplug the defrost heater on one end and check the continuity. 305175 Defrost Heater and defrost thermostat Part number 3489. If you change the defrost heater you should also change the defrost thermostat. Let me know the results. Remember above 60 degrees the defrost thermostat will show open with your OHM meter.

It's almost always the defrost heater. If you have volts to the defrost thermostat the defrost control is working. Set your meter to check ohms and remove the wiring from the heater. If anything changes when you touch the meter leads to the heater terminals then the heater is probably good, but my guess is nothing will change, which means you've got a bad heater.

Freezer section works, refrigerator becomes warm.


In the defrost circuit there are three major parts. Defrost timer, defrost heater(s) and defrost thermostat. Defrost timer failure will not put power to the circuit. Defrost heater failure will fail to defrost when the timer applies power. Defrost thermostat must be closed for defrost to take place. FIRST located the timer, rotate the Clutch head screw clockwise SLOWLY until one distinct click is heard. Timer will be in defrost mode and defrost should happen in 18-22 minutes after which the refrigeration should start cooling again. If defrost takes place and it does not go back to cooling automatically turn the screw once again until you hear the second click, unit will start. Replace the timer. If defrost does not take place in the time frame above and the unit restarts in cooling test the defrost heaters. From the heater(s) follow the wires from each end to where they plug into the circuit. Unplug them and test through the heaters with an OHM meter. You should get a reading if they are good, if no reading replace the heaters. If you get a reading on the heater(s) replace the defrost thermostat.
