Commercial Pizza Oven Tripping Power on Switchboard – Oxenford
A customer in Oxenford contacted ISB Electrical because their commercial pizza oven was tripping power on the switchboard. The oven could not be used safely because the electrical protection was operating when the appliance was switched on.
When a commercial pizza oven trips the circuit breaker or safety switch, the fault can be caused by a short circuit, faulty heating element, burnt wiring, damaged terminal connection, faulty contactor, insulation breakdown or a motor winding failure. In this case, the blower fan motor was inspected and tested.
Inspection and Diagnosis
- Checked the commercial pizza oven power supply and safety condition
- Confirmed the oven was tripping power on the switchboard
- Isolated the appliance before inspection
- Inspected the blower fan motor circuit
- Checked motor wiring, terminals and connectors
- Found signs of burning around the motor windings
- Confirmed the blower fan motor had a short circuit fault
- Confirmed the pizza oven was unsafe to use until repaired
Fault Found
The fault was caused by a faulty blower fan motor. The motor windings were burning and had developed a short circuit, causing the commercial pizza oven to trip power on the switchboard.
The blower fan motor is important for moving hot air through the pizza oven and maintaining correct cooking performance. When the motor windings burn or short, the appliance can trip the breaker, stop heating correctly, produce a burning smell or become unsafe to operate.
Repair Required
The faulty blower fan motor needs to be replaced. The affected wiring, connectors and motor circuit should also be inspected for heat damage before the appliance is returned to service.
After replacing the motor, the commercial pizza oven should be electrically tested and run through operation to confirm the fan is working correctly and the switchboard is no longer tripping.
Common Causes of Commercial Pizza Oven Tripping Power
- Blower fan motor windings short circuit
- Burning motor windings
- Faulty heating element
- Burnt wiring or loose terminal connection
- Faulty contactor or relay
- Low insulation resistance in electrical components
- Moisture or contamination inside the electrical area
- Damaged switchboard circuit protection or overloaded circuit
