I have a minimax heater, 5 years old, after winter this year, started it p cater looking everything over, it starts, cycles, the fan starts up, runs for a minute or two, then the igniter glows for a short time, then a click and the has valve opens up and gas flows onto the burner, it fires, and the fan is still running as it should be. Then , the breaker trips, everything, NO codes, no flashes on the ignitor board, nothing showing any failure. Same thing, check all wires for shorts, replaced the GFi breaker, it's on the same breaker as the pump, and has been this way since new, never an issue before, even tired a larger amp breaker, twice at 50 amps, same trip. Fan runs fine, the squirrel cage spins freely. Have replaced the DDTC as a few LEDs were bad, nothing. All wires look fine, the pool pump runs fine. As zoo. The the gas flows and it fires, you can see the flames inside, then it trips the breaker.
