New to us (2019) Keystone Bullet 220RBI.
Symptom: When running the furnace very little heat came out of the floor registers. My wife also noticed the side of the cabinet where the furnace is located was quite warm.
Diagnosis: Removed the inside cover panel to the furnace to find...
Duct #1 disconnected and fallen to the floor.
Duct #2 disconnected and fallen through the floor into the sub floor.
Duct #3 still connected.
Well that explained the lack of heat anywhere but the inside of the cabinet where the furnace is located. Luckily it was a simple fix reconnecting the ducts.
