Thread: Electric Furnace Duct Sensor?

Hi Gents This is my first post and I still have a lot to learn it seems. Just started my second year inspecting and have gotten a lot of great info from this site the last year. This electric furnace installation looks dodgy to me. Any ideas on what looks like a sensor on the bottom of the flex duct that goes into the attic. Any feedback appreciated. Peter Stapleton

It looks like a damper (motorized) typically used in a zone control system.

What a hack job that is...

My guess would be a damper motor that controls fresh air. Look for something that looks like a oversized fireplace fresh air inlet on the outside wall. If that is what it is, they should have connected it to the return air plenum. (OH, wait, we don't have a return plenum. Well just mount it next to the return filter, close enough)

I really love the control wire laying on top of the filter.

Peter,

What does The Warning Label on the wall say?

Thanks for the feedback guys. The warning label Billy had info about clearances and safety requirements in relation to working on the unit.

Yep, that's my guess too.
