Marey heater trips the circuit breaker when it starts or during operation (electric model).

Safety first: Leave the breaker OFF until the fault is found. Risk of fire or shock.

Steps:

• Inspect for leaks: Check inside the unit for any signs of water near electrical terminals. Fix leaks before restoring power.
• Check wiring size: Confirm that wire gauge and breaker size match Marey installation requirements.
• Inspect elements: Look for visible damage or burn marks on heating elements and terminals.
• Test elements (advanced): With wires disconnected and power off, measure resistance to ground from each element terminal. Any continuity to ground indicates a shorted element that must be replaced.

When to call a technician: For detailed electrical diagnosis, element replacement, or if the breaker continues to trip after obvious issues are corrected.
