Bryant Plus 90 furnace ignitor replacement

Hi all. My furnace ignitor has quit working and I could sure use a little help. The ignitor is in a very tight location. Does anyone know an easy way to remove/install the ignitor? I was thinking that this is a somewhat common problem and that the replacement would be a snap but that doesn't appear to be the case. My full model number is 350MAV048080. Thanks in advance.

John

Are you sure it is bad? Did you test it?

Yes, I'm sure. I unplugged the connector and used my multi-meter to probe the contacts and verify the circuit is open.

Welcome to the forums.

The manual may help some. With some furnaces the igniter comes out with the burner.

Thanks for the manual. Mine is slightly different than described therein. My doesn't appear to have a screw holding the bracket. I noticed the Service Manual says series G. Are there other series? Any other suggestions would be appreciated.

I ran your model number and under Repairclinic.com it shows that the HSI goes into a bracket that is held in place by 4 spring steel prongs that are part of the bracket. RepairClinic Item # 2357079
Bracket Kit - Part # 2357079 Mfg Part # 323901-701 There is a seal on the bottom of the bracket that forms a seal between the bracket and fire box. If this is correct then it is just like the one I just replaced in my Carrier unit. I used a telescoping mirror to get a good look at it and used a common screw driver to pop up the bracket. I also disconnected the Intake and exhaust pipes so I could see and have better access. My bracket's seal was dried out so I bought a new bracket ( only way to get the seal). The new bracket was a bit out of whack so I cleaned the old seal off the old bracket and installed the new seal onto it. Once you pop up one side of the bracket the whole thing comes out rather easy. I recommend you practice installing the bracket without the HSI installed. I placed the bracket into position, slid it over the opening so two end prongs (on the short side) slid into place and then with a bit of pressure snapped the other end in. I hope I explained this so that it is clear. If not pm me with your phone number if you like and I will try to explain it better. Good Luck

Thanks for the reply! Yes, that's my bracket. How does the bracket hold onto the fire box? The bracket and the seal are visible from the outside and it won't budge when I apply pressure. You mention a flat head screw driver to pry it up...which edge do I start to pry? Since the bracket is a rectangle, it has a length (L) and a width (W) so do I start along L or W? Was it damaged during the removal process?

Also, I thought about taking the intake pipes etc and that pipe is glued together and I'd have to cut it...so I thought there must be another way. Did you cut the pipe?

I'm looking for instructions to send a PM and I'll go that way after I find them.

I wish I could help further but I'd need to see your furnace.
Way too many different models to remember them all.

Thanks so much for your explanation and phone call. My heat is back up and working now. I installed the bracket and then inserted the HSI as I had a trouble seeing the slots for the kinked tabs.

For others that run into this ignitor/bracket issue with their Bryant/Carrier/Honeywell furnace. The "hole" in the sheet metal is essentially in the shape of an "H". Picture the horizontal bar of the "H" to be very thick and that's what you have. The bracket has a kinked tab that fits into the four ends of the vertical bars of the "H" shaped hole. You need to feed the bracket/kinked tabs at an angle into one end of the "H", rotate the bracket so that the other tabs feed into the opposite end of the "H" and push hard to deflect the tabs.

I then inserted the new HSI used a long flat blade screw driver to push the connector into the bracket assembly.

Remember to turn the gas back on before you test your furnace or you may have a heart attack like I almost did as I thought I now had another issue to repair. The temps are dropping fast...

Message for SaltyDog or PJMax

I am attempting to replace the hot surface igniter on my Bryant Plus 90 furnace which was installed in 2002. The igniter is somewhat obstructed by the intake PVC pipe. I was able to get one hand behind the pipe and remove the bad igniter but I'm not certain if there is a trick to get the new igniter and bracket back into place using one hand. I fear breaking the new igniter. tried to remove the intake pipe but it won't budge. Any suggestions?
