Why your commercial freezer is thermostat issue
A thermometer left inside for an hour reads 6–10°F off the setpoint, and the unit short-cycles instead of holding a steady band — that is the commercial freezer reporting something specific, not a vague fault. The fault itself is contained today; what it damages next is what makes the bill grow.
Causes, in the order we check them
- 01A temperature sensor giving bad data
- 02A wiring fault between sensor and board
- 03Thermostat contacts that have stuck
- 04A control board misinterpreting the sensor
- 05A thermostat reading out of calibration
Quick checks worth doing
Worth ruling out yourself first: compare the reading against a separate thermometer left in the same spot for an hour. Also, confirm the actual setting, and give it 24 hours after any change before assuming it's broken. If you want a firmer read on it, check the drain outlet and the pan for standing water or ice, which tells you whether the defrost water is getting out. If that doesn't clear it, a sensor confirmed inaccurate has to be replaced and recalibrated against the board, which isn't a part worth ordering on a hunch.
The visit starts with measurements, not guesses — the commercial freezer gets tested before any part is named. Whichever of these it turns out to be, the reading taken on site is what decides the part — not the symptom on its own.
What St. Augustine's climate does to a commercial freezer
Living on the First Coast means months of heat and heavy humidity, and your commercial freezer works against both. Coastal salt content works on condenser coils and exposed metal, and the summer heat alone extends compressor run time well past what the spec sheet assumes. On a St. Augustine job we check for the wear this environment causes, so the fix holds past the next heat wave.

Common questions
Answered before you call.
Is the repair covered by a warranty?
You're covered by our 18-month labor warranty and 90-day parts warranty. If the same fault recurs in that period, the follow-up visit is free.
What does the diagnosis involve?
First the fault is reproduced and measured, then you get an explanation of the failure in plain terms and what putting it right requires. Nothing is replaced on a guess.
When is a replacement the better call?
Yes. Some failures cost more to put right than the remaining life of the unit justifies, and a technician who has just measured the fault is the person best placed to tell you which case you are in.
Do you use OEM parts?
We fit OEM parts wherever the repair calls for them. Where a manufacturer part is discontinued we say so, and explain what the alternative is before fitting it.
