goodman flame rollout switch

[gmeysman]

Installed a 95 percent goodman gas hot air furnace with a 3 ton air cond system in a prebuilt home. Air cond worked like a charm but when the furnace is on the roll out switches kick out with no apparent rollout visiable. Bad rollout switches? Any ideas on what is going on. First goodman I have installed

I'd suggest rereading the venting instructions and starting there.

What is the gas pressure, temp rise, carbon monoxide and carbon dioxide in the vent?

Low air flow to the home can cause roll outs to trip.
Check the flue for blockage. You could have a wasp nest or other obstruction that is NOT causing pressure sw problems, but flue gas temps will rise.

Was it installed as a two pipe system? As stated previously check the venting for obstructions. Also check the gas pressure.

did you check out the orifice in the manifold? I once installed a furnace with natural gas orifice in them, didnt take notice that there was a propane tank around the house, neither did the sales man... later that season there was a call back.. guess what for..

I got sent back to a new install that would run for about 5 minutes then open roll out. It had an auxillary limit with the same rating so I switched them with the same result. Gas pressure was good, orfices correct, venting clear, but co super high. Ended up being to much oil left in secondary at factory.

Stick around. Not all of the mods are idiots, just me.

You'll find a LOT of homeowners ask similar questions.
