Walk in cooler cycleing

It is called short cycling. Help below

If your refrigerator is short cycling, it can be caused by a number of issues including: An incorrectly set thermostat inside your refrigerator. Dirt and dust on the coils that prevents efficient operation. Faulty capacitors or relays that prevent the compressor from staying on.

The best guess is that you have a bad thermostat. When the compressor shuts off it has to stay off for a long enough period of time for the low pressure high pressure to equalize. If it turns the compressor off and back on immediately it can't start against the heavy load created by these unequal pressures. If it will start every time after sitting for 10 minutes the thermostat is making it short cycle.

My immediate reaction would be to cut your losses and buy a new unit as sooner or later you will run into a part that is no longer available.

Most evaporator fans run all the time. This is mainly to use the air flow to assist in melting off any frost build up during the compressor off cycle. If that fan shut off with the compressor the coil will have a tendency to freeze up. :)

If it has worked for a year and your able to choose different cycles with the same result. It seems to functions with one common element failing. If the control unit cant detect how full the machine is with water it will shut down. Sounds like a water problem steming from your pressure switch. Not sure which model you have but usually it will sit on the water pump or under the console with a clear hose if under the console. If so a quick test of attaching an ohm meter set on continuity then blowing lightly to see if under pressure the switch reacts by closing if it doesnt then the switch is bad.

It is probably a failed run capacitor for the compressor. Without the capacitor, the motor can't even try to run, but it will draw extreamly high amperage until it trips the thermal overload (avarage trip time 5-10sec) after it has a few second for the safety to cool off, it will try again. Either that or the compressor truly is seized

when its running how hot are the sides the starting amps are too high and 1.5 running amps ain't bad now the the cut in cut out are too high if you look on the dial that the mid point settings that's where you should have it not on 1 1 is hot set it on the straight line that's where you should do all your testing colder settings go up not down you could be overheating the compressor by making it come on too quick the freezer should be about -10 or so do you see any gaps in the gasket

Most Likely Low on Freon. Low Pressure switch shuts That Compressor Off.

I would try to start the unit with only the fan running at first. If it stays running then cycle on the compressor and see how it does. If the unit does not operate when compressor is turne on then we have to dig deeper into that.
