carrier furnace problems..still


it might be a temp control like that, but i don't think so. when i finally got the burners to come on the fan came on and ran for a moment even though the furnace was cold. then the burners come on and the fan goes off. after about a minute the fan comes on again and all seems normal

thank you for your time and help on this , i greaatly appreciate it.

Did you find out what tripped the limit? These are safety devices and don't usually trip for no reason. You could still have a safety issue that needs to be looked at. Which limit was tripped?

the damper safty switch. it tripped and the curcuit breaker tripped when my wife was playing with all the controls..just sliding them here and there cuz she had no idea how to work the thermastat. had never had a problem till then. i heard her rapidly sliding and turning all the switches every which way.

cleaned everything inside and oiled the motor. i even put the other fan control panel back in but the same thing. fan comes on. then the burners, and the fan stops. after a minute or two the fan comes on and it works ok.

Is the flame blue and strong flame in lp or not? If it is not blue and strong may not have enough heat to heat switch to make it light.

Alot of Carrier models have a 90 sec. fan run before the burners kick on. Then there is time for things to heat up before the fan kicks on again.
