Question about Heating & Cooling

1 Answer

I have a Goodman gas furnace (model GMP 108-3). It recently stopped working. It is an hsi unit. The HSI appears to be working - I don't see any cracks or anything. When I flip the switch at the unit, the fan kicks on, the HSI gets hot and then the top burner lights. Problem is that it doesn't stay lit and it doesn't travel to the burners below it. I took out the flame sensor and cleaned it with very fine sand paper, but that didn't seem to do anything. Any ideas?

On your flame travel tube sometimes something gets in that and blocks the path. Now this is what I found one time when same problem happened.

I took it apart and found a dead **** roach in the path. Took the bug out and it worked perfectly.

I don't think you have to take it apart just take something and run in the path like a tooth pick or a small screw driver. Maybe a air compressor air gun just enough to blow the path out. let me know if that helps you. ken

I hope this is what you are talking about as I read your post 2 or 3 times to get a idea of what it is exactly.

Hello, Check to see if you are getting between 40 and 90 ohms on the ig niter, just turn off power to furnace and unplug molex connector at igniter. After u unplug igniter check the Resistance of the ignitor and if it is extremely high like 180 ohms or higher than you will need to replace the igniter.

I have a furnace goodman, the hsi glows then i hear a click ( there is 24 v in the gas valve after the click ) but the burners never ignate.


Hello, the first thing to check is if you are getting gas flow to the burners, if you are than the ignitor is bad and must be replaced. if you are not getting gas to the burners and are getting 24 volts to the gas valve then the gas valve is bad and must be replaced.

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.

This is potentially a very dangerous condition. First of all, think of the design, the flame sensor is there to shut the valve off if there is not good ignition on all burners. From what you said, it keeps the first burner on with no ignition to the other two? Do you smell gas when this occurs? There are two problems here, lack of flame cross-over to the left and your flame sensing safety failing. If the valve shuts off in a timely manner, then I would say clean the cross-over slots and verify manifold pressure is correct. The latter is more likely. If the safety is failing and not shutting off the gas valve, the control circuit board is defective. The wire coming from the flame sensor should return to a specific point on the control module and it reads micro amps to detect flame. Furnaces will either have a remote sensor as you describe or use the HSI, but not both. If your control module has been replaced, verify the sensor is connected correctly. Hope this helps and please rate my answer.

Will not lite. checked hsi without touching


Sounds like air in the line, just crack the gas line coupling or connection till you smell the gas scent and retighten lines and wait a few minutes till the air clears around the unit and fire it back up.!T Y V Much!

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?

I seem to be working on the same problem. What I found bothers me. As a safety feature, the hot surface igniter, (HSI), is in series with the gas valve. If the HSI is dead, then there is no gas flow, which is a good thing. However, if the HSI has increased in resistance, as mine has, it still allows the gas valve to open partially. Not quite enough gas flow to support an ignition but, enough to allow gas to escape. I would suspect your HSI increases resistance after you get a flame causing the gas valve to close long enough for the flame to stop, then the HSI decreases it's resistance enough to allow the gas valve to partially open. Please verify this on your own as I am just a regular home owner myself.
