My Mr Heater Big Maxx garage heater suddenly stopped working, and when all is said and done the board blinks twice. According to the inside panel of code meanings, 2 blinks means "System lockout, failure to detect or sustain flame".
Here is what happens. I turn the gas on going to the unit, I turn the power on and then turn up the thermostat. Right away the unit starts (kind of a low hum) and the board light is constantly blinking normally. I will hear a clicking sound (which I assumed when it was working was the call to engage the blower fan). About 20 seconds later it will click again and I think it does it one more time. The unit will ultimately shut itself off and there is a strong gas smell. I presume this is just coming out of the chambers after the unit turns off as the gas has no where else to go.
This just started happening out of nowhere and the unit was working fine w/out any issues yesterday.
If I trip the breaker for a few seconds, the control board will flash three times (once) and then immediately go to a normal 1 flash mode and begin the start up procedure as descibed above. I cannot hear or see the igniter.
Apparantly 3 flashes means the pressure switch is opened or closed. I have bypassed the switch per the troubleshooting guide (http://www.mrheater.com/troubleshooting.aspx?id=26) with no luck.
Any advise on how to fix this is appreciated.
