    Default Determining if freezer defrost heater is bad

    I have a GE GSL25JFPBS side by side where the defrost coils keep freezing up. I changed the defrost thermostat. I checked continuity on the old one and it was continuous below freezing and at room temperature, so I wonder if the circuit stayed closed long enough to burn something out.

    Replacing the defrost thermostat alone did not fix the problem. I'm looking at the defrost heater now, which I can see has some carbon buildup in it.

    I saw a Youtube video that said check the resistance and make sure it has less than 50 ohms. When I check the resistance, I get about 20 ohms. When I test it for continuity, my multimeter doesn't beep. How do I know if it needs to be replaced?

    If it's not the defrost thermostat or defrost heater, what should I check next?
