Witch blower is running, the inducer or the systems blower?
System blower could mean the the high limit is opening and shutting down the systems gas train, I would check this out first.

The other problem could be with the pressure switch for the gas train, it is supplied from the inducer motor, check to see if it is operating fully.

HSI boards do go from time to time, this sounds more like a system control problem.

Goodman GMP075-3 not igniting. Everything cycles as it should but HSI does not glow. Thermostat is set to heat, temp approximately 10 to 15 degrees higher than room temp, blower motor starts, relay clicks...


The flash code is due to the furnace not proving flame 3 times in a row. If you have a multimeter you can ohm the ignitor out to see if it is good. Depending on the type (silicon Nitride or silicon Carbide) you can verify if it is good. A silicon Nitride ignitor looks like a small thin straight bar type will ohm @ 11 - 18 ohms, a carbide ignitor looks kinda like a tuning fork (sorta) will typically ohm @ 40 - 92 ohms. anything outside of those ranges will require a replacement.

Gooman heater connected to electronic lux 500 thermostat. no response from heater at all. tried changing batteries in thermostat.could thermostat possibly be bad. had both for approx.11 years


Remove t-stat and remove red and white wires and connect them, if unit starts then it was the t-stat.
If not go to furnace and remove same two wires at furnace and jump out at circuit board or connect wires FROM furnace, if it starts the problem is in wires.
If you have power to furnace?? and nothing happens it is either a bad board or inducer motor (little one) is not starting. Remember that their is a fuse on corcuit boards that need to be checked.

Bad control board?


This is a good one! I would check for a blocked vent or intake pipe first. Also check to make sure the condensate lines are free of moisture or debris. What is the code for three blinks?
