Why your Randell refrigerated display case is thermostat issue
On a Randell refrigerated display case, thermostat issue usually announces itself like this: temperature inaccurate, cycling abnormally. Bad thermostat or temperature sensor. More often than not it traces back to a bad control board. Left unaddressed, food or stock can spoil within hours.
Most likely causes
- A miscalibrated thermostat
- A bad control board
- Failed temperature sensor
Known Randell refrigerated display case weak points
- Clogged condensate drains causing water pooling inside the cabinet
- Cracked or worn door gaskets losing seal and forcing compressor overwork
- Dirty condenser coils causing short-cycling and poor temperature hold
- Condenser or evaporator fan motor failure leaving product too warm
Quick check — and when it's not DIY
Worth checking yourself first: confirm the temperature setting itself, and give the unit 24 hours after any adjustment before assuming it's broken. Also, compare the reading against a separate thermometer placed in the same spot for an hour. Once you've ruled that out, a sensor that's confirmed inaccurate has to be replaced and recalibrated against the control board — guessing which part is at fault wastes a parts order.
