End of heating season this year the exhaust/combustion fan seized. ordered new one. Went to install it and got an arc to chassis. (I didn't unplug the unit). Started the troubleshooting procedure. Startup timer module is bad. ordered new one. Finished troubleshooting and auger timer bad now. ordered new one. Checked ohm reading on ignitor and it reads 61 ohms. 11 ohms over book top end setting. This will be the 12th heating season. Question 1. Is there a way to check the timer modules with an ohm meter? Question 2. The old auger module ran with the ignitor. Can I take the ignitor out of the system? I don't want to have to buy a new one.
