Blodgett Conveyor Pizza Oven Error Codes
HIGH TEMP
What to do:
Wait for the oven to stabilize and for the display to show READY before you start loading the product. The HIGH TEMP error code may occur after the temperature setting is lowered or after operating the unit, causing the cavity temperature to temporarily rise above the set temperature.
HIGH TEMP LIMIT
What to do:
- Turn the oven off.
- Stop loading food.
- Allow the equipment to cool.
- Follow the shutdown and restart instructions in the model-specific manual.
HIGH TEMP PANEL
What to do:
- Turn off the oven and allow it to cool.
- Make sure ventilation openings aren’t blocked.
- Check for grease, dust, or nearby objects restricting airflow.
- Confirm that the oven is installed with the clearances required by its manual.
PROBE OPEN or PROBE SHORT
What to do:
- Turn the oven off.
- Record the complete error message.
- Don’t continue cooking if the oven can’t accurately monitor temperature.
- Contact an authorized service provider.
HEAT ERR
Possible areas requiring inspection include:
- Gas or electrical supply
- Ignition components
- Heating elements or burners
- Temperature sensing
- Control output
- Air circulation
FAN ERR
What it means:
The control called for heat but detected a fan failure. On some Blodgett controls, pressing TOGGLE/CLEAR clears the alarm so normal operation can resume temporarily. Persistent fan faults require professional service.
FANC ERR
What it means:
This error code indicates a contact failure in the fan control circuit on compatible Blodgett pizza oven models. The alarm can be silenced with the TOGGLE/CLEAR key, but the code may still remain on the display.
What to do:
If the error returns, discontinue operation and arrange for an authorized service technician to take a look.
DOOR OPEN
What to do:
- Close the door completely.
- Check for pans, food debris or other obstructions.
- Inspect the gasket and latch for visible damage.
- Contact a technician if the door is closed but the message remains.
Other Blodgett Oven Codes You May Encounter
Some Blodgett oven models used for specialty pizzas may display additional error codes. These codes aren’t universal, so verify that they apply to your exact controller.
Cavity Probe Error
What it means:
A cavity probe error occurs when the probe is reading below 32°F or above 575°F. This can mean that the probe is providing invalid readings or there’s a sensor-circuit problem.
What to do:
Stop using the oven and have the probe and associated wiring diagnosed.
Cavity High Temp Error
What it means:
This error occurs when the cavity probe reading exceeds 565°F or rises 150°F above the set temperature.
What to do:
Turn off the oven, allow it to cool and request service before returning it to production.
Communication Error
What it means:
This error code means the controller lost its digital communication signal from the relay board. Have an authorized service technician check the connections and communication cable.
Do Blodgett Deck Pizza Ovens Display Error Codes?
Not all Blodgett deck ovens will display an error code. For example, the Blodgett 900 Series provides a troubleshooting guide rather than a universal error code list.
Common symptoms include:
- Oven won’t heat
- Burner won’t ignite
- Pilot won’t stay lit
- Oven temperature is too high or too low
- Baking is uneven
- Pizza bottoms cook too quickly
- Recovery time is unusually long
- Excessive soot or an abnormal flame is present
How to Reset a Blodgett Pizza Oven
There’s no single reset procedure for all of the Blodgett pizza ovens. The safest, general approach is to follow these steps:
- Write down the error code.
- Stop loading food.
- Use the normal power control to turn off the oven.
- Allow the oven to cool if the message involves excessive temperature.
- Check for an open door, blocked vent, incorrect temperature settings or dirty air intake valves.
- Consult the manual for the exact model.
- Restart only if the manual permits it.
- Call an authorized service technician if the code returns.
Information to Collect Before Calling for Service
If you have the right information ready when calling a technician to diagnose the issue, they can do so more efficiently.
Have this information ready:
- Full model number
- Serial number
- Complete error message
- Current set temperature
- Displayed oven temperature
- Whether an alarm is sounding
- Whether the conveyor, fan or burner is operating
- What happened immediately before the code appeared
- How often the problem occurs
- Any recent cleaning, maintenance, installation or power interruption
How to Prevent Blodgett Pizza Oven Faults
- Keep ventilation openings clear - Make sure the cooling air inlets aren’t blocked.
- Follow the cleaning schedule - Ensure all crumbs, flour, grease and leftover food debris is removed.
- Monitor baking performance - If you notice a gradual increase in bake time, delayed recovery or temperature swings, this may relay a problem before the oven displays a code.
- Inspect doors and seals - Ensure all doors close correctly and that the gaskets aren’t worn.
- Schedule qualified maintenance - Have an authorized service technician check the gas pressure, burner performance, calibration, safety limits and more at appropriate service intervals for your specific unit.
