Why your Randell walk-in cooler is thermostat issue
When a Randell walk-in cooler is thermostat issue, here's what you'll usually notice: temperature inaccurate, cycling abnormally. Bad thermostat or temperature sensor. Nine times out of ten it comes down to a miscalibrated thermostat. Left unaddressed, food or stock can spoil within hours.
Most likely causes
- Failed temperature sensor
- A miscalibrated thermostat
- Stuck thermostat contacts
Known Randell walk-in cooler 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
Start here — it costs nothing and rules out the easy cause: compare the reading against a separate thermometer placed in the same spot for an hour. If none of that changes anything, if the setting's right and it still misreads, the sensor or board needs testing with a meter, and a wrong guess here means paying for a part that wasn't the problem.
