NOT DEFROSTING I ohmed out the heater and it was good. So I changed the board out from all the reading I had done it pointed me to that. The evap fan works fine But I don't know if its working intermittently. Its my fathers. The vent has no product blocking it. It wouldn't be the defrost termination switch, because its going into refrigeration. The model is G.E.#GSH25JSTCSS HELP !!!

Hello,


Do you see frost built up on back wall of freezer? if so it is not defrosting and this is what needs to be checked, remove back wall of freezer and check these;
Defrost heater-- it usually is at bottom of the evap. coil, to check it remove wires to it ,use a meter set to the lowest ohms setting and check for somewhere between 10-50 ohms if that is what yours is its good if meter reads OL replace defrost heater

Defrost thermostat-- it clips to the top of the evap. coil and is metallic,round , about the diameter of a quarter with a plastic side with 2 wires coming from it(do not confuse it w.thermister),remove wires and check for ZERO ohms WHEN TESTING IT MUST BE COLD so check it when frost is built up,IF meter reading is OL (WHEN COLD) its the problem

Defrost timer or defrost control if has digital display to show tempature
check timer(it could be anywhere except in freezer) by turning till you hear a click,the defrost heater should come on within 5 minutes if the heater does come on the timer is the problem and needs to be replaced,if the heater does not come on the above mentions parts (heater/t-stat) will be the problem.
defrost control is hard for unskilled lay persons to check SO IF heater and defrost t-stat are good replace control I hope this will help you figure out what is wrong with your refrigerator, Gene

What the problem could be when your freezer works but ref. section is warm

Hello,

Is your freezer working well? is their a lot of frost build up on back wall of freezer? if yes its not defrosting and this is what you can check

Defrost heater-- it usually is at bottom of the evap. coil, to check it remove wires to it ,use a meter set to the lowest ohms setting and check for somewhere between 10-50 ohms if that is what yours is its good if meter reads OL replace defrost heater

Defrost thermostat-- if clips to the top of the evap. coil and is metallic,round , about the diameter of a quarter with a plastic side with 2 wires coming from it(do not confuse it w.thermister),remove wires and check for ZERO ohms WHEN TESTING IT MUST BE COLD so check it when frost is built up,IF meter reading is OL (WHEN COLD) its the problem

Defrost timer or defrost control if has digital display to show tempature
check timer(it could be anywhere except in freezer) by turning till you hear a click,the deforst heater should come on within 5 minutes if its good,if defrost doesn't come on its either the of the above parts (heater/t-stat)
defrost control is hard for unskilled lay persons to check so if heater and defrost t-stat are good replace control

Hope this helps,

Remove the freezer back panel and replace the defrost heater and defrost thermostat.

Not a board issue if you have a noisy fan motor. Noise equals friction and friction equals loss of speed.

Check the BLUE wire from the temp control to the ORANGE wire of the defrost timer for continuity. That is the complete fan circuit. You should read the resistance of the Evap fan motor. If you do not read resistance suspect the pins of the evap fan motor connector or... the Unbilical harness from near the evap to the icemaker and the evap fan. The connector pins of the Evap fan motor connector (Freezer connector) are notorious for failing.

do the coils look white or are they so totaly blocked with frost that you cant see them how old is the unit and is it electronic control
