Freezer runs only when I turn knob

My Frigidaire frs26rlecs4 has been freezing all things fine, after a while though I will wake up and the freezer has melted. I noticed today that it starts to freeze again if I turn the knob either to the max setting or any other way. Basically if I put the knob at (6) which is max it freezes but when the temp reaches it’s peek it stops freezing but it doesn’t start again unless I move the knob any direction. Does anyone have any idea what the issue might be? I’m a big believer in fixing it myself if I can.

thank you so much for you’ll help!

Check that the freezer thermostat, part #21A Controls diagram is OK.

Here’s an image of the wiring diagram that may help.

If the temperature in both the refrigerator and freezer compartments get to the correct temperature then it is normal for the compressor to be turned off. What should happen is that when the temperature rises in either compartment above a minimum pre-set temperature, due to normal activity e.g. doors opening a lot etc, then the compressor should be restarted. It is the thermostats that signal the temperatures to the controls.

Agreed. It sounds like your thermostat has 'wandered, and no longer operating correctly. The fact that messing with it causes it to resume operation confirms that this is the problem. Recommend replacing, its not a very complicated or difficult process. Just make sure you unplug the unit before swapping them out, and put the new one in exactly as you took the old one out. Probe in the same place, wires in same locations, that way it operates correctly.
