Correction: I was referring to *motherboard, or inverter PWB.

I am not sure about the triac either other than it varies the wattage for one of the heaters. The other is controlled by the heater relay on the board. So I assume if the triac were bad you would still get heat from the other heater.

Can you tell if the blower is actually running or not?

I think it is either in the blower motor or the inverter. As I said before, the inverter is the only thing that will cause all three error-codes but I can’t say for sure if it is your problem or not. I have been through this before and have seen the motor check ok ohms wise so I change the inverter then still end up having to replace the motor to get it going. I have called GE technical assistance for this reason and all they tell me is to replace both, which is not helpful at all.

That's what I see in the diagram on the two heaters and the relay and triac.

The blower is not running. It only jerks quickly twice or thrice.

I think it is either in the blower motor or the inverter. I think I'll go for the motor first, then inverter. I'm not just sure where to get the inverter replacement. I'll check the store nearby this week.

Thanks for your help, applianceman.

Applianceman,

Do you know the part number for the Inlet Thermistor? I called up the error codes and it stated...

1) "There is a problem with the inlet thermistor. Please check and replace if needed" (something like that)

2) "There appears to be no gas flow. Please check the valves and connections."

These are the two items that came up.

Your help is greatly appreciated.

I am having the same problem and this thread has been really helpful. I discovered that you can actually test the motor without disassembling everything to the point where you have access to the blower motor. The red/blue/yellow wire pairs lead to the CNI5 connector on the inverter board. So I took the connector off (it says blower next to the connector as well as CNI5) and tested the pairs there. Got the same ~14.9 ohms there as I did right at the motor.

I think it is either in the motorized infiltrator engine or the inverter. As I said before, the inverter is the only factor that will cause all three error-codes but I can not say for sure if it is your issue or not.....

Thanks Applianceman for the info. After the motor checked out I was left with the decision to replace the inverter or the motor. Based on your earlier posts I decided to try the motor first and this fixed the problem.

Your welcome!

Good job on the repair.
