Question about Goodman CLJ30AR32 Air Conditioner
Have been getting a code #33 on my Bryant 355MAV 100k btu furnace, Evolution controls (installed new 2006) every heating season for three years since we built the house. Installers solution was to turn down gas pressures (lp) which, while allowing the furnace to run, ultimately led to heat exchanger clogging (soot)and replacement (parts covered under warranty, labor $1,500 not covered). Control Board and personality plug also replaced. Now back to the same code #33, just replaced fan limit switch with same OEM model limit switch - same problem. Furnace will run fine if I jumper fan limit lead wires. Otherwise, I have to go down and turn breaker switch off then on again to clear the code 5-6 times per day. Output temp at top of plenum is 120 deg, return air 64 deg. Limit is not suppossed to trip until 180 deg! Return clean, new 30 day filter (not HEPA), 2 returns, one each side of return cabinet, one 14" and one 20". Installer is now out of business and I have been through 2 other service companies. Bryant has been very little help, other than covering parts under warranty - they just keep suggesting other parts to replace.
Any help appreciated.
'Limit or flame rollout switch is open'. In my case, the flame rollout switch had tripped due to an overheating? I had to push the button between the wire leads to reset the switch. Then when I turned the power back on, the furnace started up like normal.
Why did the switch overheat and trip? My current theory is that there was a rubber grommet around a pipe near the switch that had slid down and was no longer sealing the furnace?

Make sure the unit is properly set up (jetted/orifices) for LP. It sounds to me like the unit is setup for natural gas and is being used on propane.
