Why your Marsal & Sons pizza oven is thermostat issue
Here's how thermostat issue typically presents on a Marsal & Sons pizza oven: temperature inaccurate, cycling abnormally. Bad thermostat or temperature sensor. Nine times out of ten it comes down to a miscalibrated thermostat. Left unaddressed, the kitchen loses a station it can't work around.
Most likely causes
- A bad control board
- A miscalibrated thermostat
- Wiring fault to the sensor
Known Marsal & Sons pizza oven weak points
- Uneven deck temperature and hot spots
- Pilot outages from improper ventilation
- Slow heat recovery on large stone decks
- Burner venturi fouling and thermostat/safety-valve faults
Quick check — and when it's not DIY
Start here — it costs nothing and rules out the easy cause: 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, 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.
