Heil furnace inducer vibrating, capcitor handling question


You guys crack me up! I'm going to replace the inducer provided I don't have bigger problems with my burners cycling every 1:20. Being discussed in another thread....

Heil furnace inducer vibrating, capcitor handling question


Digger- I have that exact model - I installed the system in 1990 only mine has the Sears Kenmore brand- It is Heil_Quaker manufacture. I have replaced the exhaust blower since then- When the first one bombed I took it apart to see the impeller blade scraping the inside of the ABS case causing it to melt in places (it is a high speed fan) which off-balanced the fan and made quite a racket in vibration. That capacitor was easily discharged in a few minutes after killing the power and shorting with a screwdriver.

Yeah that's what happened to my original unit. The metal blades rusted and scraped the sides of the housing. This one was the replacement to it (plastic blades) and something isn't right about it now... bearing or unbalanced blades i'm sure. It makes more of a muffled vibrating sound instead of a scraping sound. I can feel it when I hold on to it.

My other problem:
Can this cause my burners to short cycle... 1:20 on, 1:00 off, 1:20 on... consistantly over 20 minutes, all the while the blower is running and the stat says "system on". Also the supply temp is 140 on, 160 off, 140 on.... hitting the high limits all the time - but why? Make comments at the other thread short on/off cycle times for burner/inducer

A bad motor for exhaust can cause short cycling, Also, not enough air flow, cracked heat exchanger, over fired , etc, etc, If I remember correctly. This furnace is 18 yrs old ??? I would suggest you call a HVAC contractor to check it out

"If you remember correctly". Do you know or don't you? Don't get me started.

What ever happened to following through on the basic troubleshooting steps before calling in the calvary. Sure I could call a contractor if I had the money. It's the easiest way out.

This motor is running very well except for the small vibration, I suspect the bearing is starting to go. It's not stalling, the blades aren't rubbing on the plastic shell and it's pulling exhaust out of the exchanger at normal speed. I'd like to understand how my blower symtoms can cause the short cycle. If it was worse I could see it. Again that's where I'm willing to learn something...

Before I replace the blower or call a tech I want to eliminate as many possibilities as I can. That's what this board is about. Yuri and beenthere had some good air flow suggetions to look into. I'll do that tomorrow. If it comes down to it I'll replace the vent blower myself - I can't afford the markup and labor right now. Nor can I afford to replace it without eliminating the other possibilities first - that I can check out. I don't want to replace the blower and find out it wasn't the problem, or that it was a simple solution that I could have done myself. I like to be diliget and take it a step at a time.

Regarding the fan blade- mine is plastic as I think they all were due to the caustic nature of the exhaust condensate. Fast plastic spinning next to a plastic shell doesnt take long after a touch or 2 together to melt off some plastic- then you have the off-balanced wheel causing a rumble. Regarding the cycling, look towards the electronic fan speed/limit control. Mine went bad and I replaced it with an exact replacement however- I had to tweak it many rounds until I got it so the cycling was just right. It was hard to establish how well the small dials worked.

Dude don't beat on the Pros. Your getting free info. If yo can't respect the pros who are here with out pay then go ask for help else where.

Keep it civil.

Absolutely, I agree with you 100%. It's the last thing I want to do and I can garuntee you I appreciate the pros help more than anyone else on this board. Really, I am greatful for everyone's help!!!!! Thank you again everyone!!!!

Late last night in my other thread I got lambasted by plumber101 for asking questions. Yuri's and my posts got crossed, and apparently Plumber101 thought I was blowing Yuri off - not the case at all. It didn't sit well, especially on a DIY board. I explained what had happened and explained what my intentions were and how I appreciated the pros help here. From the other thread:
"Yes I plan on listening to yuri and following his suggestions - as well as any other pros here - I appreciate their input very much."
"If the pros didn't want to graciously help people on forums like these they wouldn't be here "

Sorry it spilled over to kenmac. I just want to go through whatever I can to fix this civilly, before I call someone in. I just want it to work both ways. I can't afford to waist money right now. I don't want this to get blown out of proportion. Again, I am sorry if I offended anyone, including Plumber101 and kenmac.
