The short answer
Establish whether the machine has a dial or a display. On a dial machine, check the setting and the supply. On an electronic one, reset at the breaker and look for a latched alarm. Confirm the cabinet temperature with a thermometer either way.
What you see on a secondary machine
- A dial that has been knocked to a different setting — Very common when things are stored around the machine.
- Nothing running and no display to consult — A mechanical machine with a supply fault.
- A latched alarm after a power interruption — Clears with a reset.
- Panel frozen on one reading — A hung controller.
- Cooling unchanged by any dial adjustment — A thermostat fault.
- Not this fault: warmer cabinet in high summer — Read the cooling page for secondary machines.
Ranked for garage and basement machines
- Dial knocked or set to the wrong position — First on mechanical machines.
- Supply interrupted at a shared breaker — Second, and it looks like a dead control.
- Latched alarm or hung controller after an outage — Third on electronic machines.
- Thermostat drifted with age — Fourth, and typical of an older cabinet.
- Damp affecting a panel or its connections — Fifth, and specific to humid rooms.
- Main board failed — Last, and rarely worth repairing on an old second machine.
Work through it in this order
- Read the dial or the display and note the setting — Someone may simply have moved it.
- Check the breaker and the outlet under load — Shared circuits trip when tools run.
- Switch the machine off and on to clear a latch — Only after checking the cabinet.
- Measure the cabinet with a thermometer — A dial position is not a temperature.
Owner-side steps
- Note the dial position, then set it to a mid position and wait — Give it several hours before judging.
About 20 min
- Check the breaker fully off and on and test the outlet — Garage circuits carry more than they should.
About 15 min
- Read a thermometer in each compartment — It is the only honest measure on a dial machine.
Tools: thermometerAbout 25 min
- Keep stored items from leaning on the controls — Dials are easily knocked in a storage room.
About 10 min
- Dry and ventilate the space if the panel area is damp — Moisture affects connections over time.
Tools: clothAbout 25 min
- Stop before opening a console or a thermostat housing — Mains wiring sits behind both.
Older machines in damp rooms
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Keep the refrigerator at or below forty degrees Fahrenheit and the freezer at or below zero degrees Fahrenheit wherever it stands. Do not run the machine from an extension lead, and do not operate the controls while standing in water.
When to call
Call when the dial has no effect on the cabinet, because that points at the thermostat, or when an electronic panel stays dead after a reset with the supply proven. On an old second refrigerator, ask about part availability and the total price first: for many of these machines the sensible answer is replacement rather than a board.

Scope of this page
Generalized across refrigerator families under this badge, written for older secondary machines in garages, basements and outbuildings; where a family-specific or model-specific page exists it is the narrower answer. Not here: code tables, thermostat specifications and board part numbers.
