Adding to the question of Defrost Timer above... I rotated Defrost timer to start of defrost and within a couple minutes the heater element was too hot to touch. …So I guess the Heater timer circuit and the heater element is working! The Evaporator core was defrosted within several minutes, but it did not look like the dial on the defrost timer had rotated very far, so I rotated it until I heard the click and then the compressor and can could be heard turning on. The Evaporator core then got cool and the heater element chilled down.

Hello,
I have a Kenmore upright freezer in my basement (model: 253.22042410) that is exhibiting a cycle of interesting behavior. It will warm up to just about or above freezing (32-38F) over a series of hours, then run continuously until the temp dropped to about -10F. Then repeat this every day or see (See image provided from my temperature monitoring app)
1. Visually confirm if the Evaporator coils inside the freezer are frosted over (Likely a sign of the Defrost heater or timer not working)
a. Lite but even frosting across the whole coil after running for hours.
2. Test the Defrost heater for continuity. If is does not, this could be the cause.
a. Confirmed to have continuity
3. Test Thermostat’s thermistor for continuity
a. Confirmed to have continuity. (0.0 resistance even with hand on metal tube.)
What could be the root cause of this issue?
1.) Relay?
2.) Capacitor?
3.) Defrost timer? (I see this rotating over time, and I have not yet seen an iced up evaporator coil.)
