Hello,
I have a Bryant Plus 90 350MAV furnace that won't ignite. I am getting a code 33: Limit or flame roll-out switch is open
It says to check for:
- defective blower motor or start capacitor
- loose blower wheel
- inadequate combustion air supply
- open flame rollout switch or fuse link
- dirty filter or restricted duct system
- defective switch or connectors
At first, the blower motor was making a loud buzzing sound so I replaced it and the capacitor. I checked everything else they said to check (including replacing the filter, flame rollout switch and pressure switch) but am still getting a code 33.
When I power it up the blower motors starts up but it is stuck on code 33 and never even tries to ignite. Any ideas what else I can do to fix this?
Thanks,
Chris
