Looking for the next part to troubleshoot. I have the front case off (massive ice storm in this area of North Dakota, thought it was from blocked intake, nope.) and this is what happens. 1. I flip power on. 2. Ventilation fans turn on 3. Blower exhaust fan turns on 4. SOMETIMES - element heats up 5. EVEN FEWER TIMES - Flame kicks on for about 1 second. Shuts off. 6. Exhaust fan shuts off, vent fans stay on 7. Free Air Conditioning in the winter! >.< The inconsistancy confuses me. I replaced the Air filter a couple days ago, but I went a while with an old one, as I primarily use wood heat, this is my backup. Side note - We have been having power grid issues, - Ice on wires with massive buildup - So the power has been flickering for 36 hours, and seems to have finally calmed down. Havent lost power in 8 hours now. But this issue existed for the last year, but only now will the flame not stay on. I cant get heat at all as of today. What should I do first?

Just had my boiler cleaned last week. As part of the cleaning, the service technician checked the transformer by placing a screw driver across the 2 high voltage clips. He noted that since there was not a good spark arcing between the clips, the transformer was too weak; it would need to be replaced. Unfortunately, he did not test the actual voltage output of the transformer, and I did not think to ask him to do this. He also noted that the Franceformer I had was rated for 10,000 volts and should be replaced if the volts drops down to ~9,500 – to 9,600 volts, even though 9,200 volts would be sufficient for proper burner ignition. The Franceformer (according to the service technician a tar filled iron core transformer) was replaced by a Carlin Electronic Ignitor made for the Weil McLain QB 180 burner (Model 41000S0WM). Now I'm curious as to what the actual voltage output was for the Franceformer. 1. Is there a way to test the transformer voltage now that it is disconnected from the burner, and if so how? 2. What kind of a test device is needed and what is the device connected to – the 2 wires for power to the transformer, the 2 high voltage clips, or both? 3. If the transformer can be tested, then will the voltage shown under test be the same as the voltage generated for proper burner ignition if the transformer was still on the burner? Thanks for your input.
