for Hilliard, OH
I found furnace locked out on code 13 and 34. Found roll out switch tripped. Reset switch and performed combustion analysis. Within seconds had between 2500-3800 ppm of CO. Shut furnace down. Removed exhaust and retested to verify exhaust was not clogged. Same results occurred. Customer chose to replace furnace.
customer stated the 2005 Goodman furnace would not turn on. Found system getting 120v. But furnace not turning on. 3amp fuse was blown. Replaced fuse and system turned on properly. Checked all wires. No breaks or exposed wires. Door switch is popping and probably causing breaker and fuse to pop. Ordering part.
