Intermittent Igniter Issues (natural gas, Armstrong Air Ultra V)

Here's the sitch.


I've replaced my igniter 3-4 times in the last year. Figured I'd just gotten cheap ones. Maybe I got oil on it, maybe chemicals/moisture from nearby washing machine/shower (there's talk of this online, idk). Anyway, I bought a beefier one and installed it carefully. It seems like it's failing again (4 weeks later), and I'm starting to suspect it's not the igniter. I'm wondering if it's a faulty board or something. The unit is quite old. I've had it at least 10 years in this house.


Here's what's happening right now. The unit will randomly decide not to ignite. The element just doesn't glow when this happens. I can shut the power to the furnace off for about 30 seconds and then switch it back on. This can solve the issue for the day—or sometimes just one cycle. Then I have to turn it off/on again in order to get it to light.


Air filter is good. Pressure sensor seems fine, since the unit triesto ignite the gas 2-3 times before deciding something isn't working right.


I've looked around online a lot and can't seem to find anything about this specific issue.


Any help would be greatly appreciated.


Thanks!.

Answer:

Maybe a bad board. Look for cracks on the solder points.

I definitely recommend TwinTech!

by Trevor Owens on Twintech Heating and Cooling

I returned from vacation to find my AC unit on the Fritz. After calling way too many places I connected with TwinTech. I’ve used the company in the past for my furnace so I was happy when I recognized Greg at my front door. He’s great and the service is always top notch. I’d highly recommend using twintech for honest, superior service in the Durham region. Thanks!

by Nicole Alain on Twintech Heating and Cooling

I called Twin Tech when my air conditioning stopped working. Greg came over to diagnose the issue - the same day. He was able to diagnose the issue and resolve it quite quickly. Although it was a quick fix, Greg was very thorough in explaining the issue and provided great advice. Not to mention, I felt very comfortable having Greg in my home - which I consider very important when hiring a service provider. Twin Tech will be my go-to from now on. Thank you!!

Twintech Heating & Cooling installed my furnace in 2022 and in fall of 2023 installed my Panasonic Heat Pump. Greg and Mitch did a great job. Helped me through the rebate process. Super happy with the Heat Pump. Only used my furnace 5 times this winter. Energy bills lower, carbon emissions lower.Thank you Twintech. I recommend highly!
