GE Profile Arctica PSC23SNGA Defrost issues. I am changing the evaporator fan because it tested low. I’ve checked many other items with the mulitmeter, so far ok. QUESTION Testing for ohms on the defrost heater and bimetal line is it ok to get slightly less… my reading is 19.8. Is that bec older control board? or does it matter? I am thinking of switching out control board as well, though most of it is testing fine. I am also curious how to test for a wiring problem between bimetal and control board? Would the 19.8 ohms be a natural degredation for the control board? ALSO i lost my service tech data sheet. Is there anyone with one or where can i find it? thank you
Generally speaking, an ohm reading within 10% of the expected value is considered acceptable for an AC-powered heating element. Ambient temperature can affect resistance slightly, so a small variation is usually not a concern.
To check for a wiring issue between the bimetal and control board, you can test continuity through the defrost circuit starting from the main control. This can help identify if a wire is broken or has high resistance.
The model number PSC23SNGA isn’t pulling up directly for me. If you can confirm both the full model and serial number, I may be able to locate a wiring diagram or tech sheet. In the meantime, here’s a link showing similar models that may help narrow it down:
I guess the psc23Snga… the big s must be for stainless steel. Please if you have a wiring diagram or service manual, thank you. Also… what color wire nuts for high temp bimetal thermostat?? thanks
Would it be possible to send a picture of the model and serial tag? Unfortunately, several different models come up with the model number provided. If the tag shows PSC23SGNA, this diagram can be used as a reference. The defrost circuit would be tested from the blue wire at Tab 2 to the orange wire at connection J7 pin 9.
Also, since wire nut colors can vary by manufacturer, be sure to check the packaging—look for one that specifies compatibility with 14 to 18 gauge wire.
This may help you also.Full model number would help:http://www.uncleharrywizard.com/nephewclub/wizardfrig/ge_2020/diagnosing-electronic-refri.pdf
