Hi new to DIY and this is what brought me here
I have a Carrier NG furnace model 58SCX and have been having some issues
The furnace will lockout when I'm not home so when I turn it off (light switch next to furnace) it will restart
The blower runs for about 60 seconds
Draft motor will start once mail blower turns off
the glow surface will glow for 20 sec or so
burners will ignite then turn off really quick
SO I read the manual and it says I might have a problem with the flame sensor, I clean out the burner area with air compressor nozzle.
The furnace works better now, won't fire every time though but it does fire more often then before.
SO now I get more aggressive in cleaning it out.
I remove the exhaust line and hook a big shop vac to it. I get quite a bit of water and some other debres from the exhaust. I do the same to intake and nothing
I blow out the water lines with compressed air and get more water out, I accidently shoot about 90 psi to the pressure switch, I think I killed it
now the igniter won't glow at all, I stick a screwdriver in the pressure switch and the igniter glows and burner ignite perfectly every time....huge improvement!!
but now my pressure switch is toast, I tape the 2 wires together and now the furnace is working flawlessly...igniting every time and running like it should.
was the pressure switch the problem? Or should I buy a new one and see if maybe I still have draft problems? The switch is 120 buxs
Would the pressure switch cause my first problem of the flames going out right away?
the switch # is FS6595 from tridelta ind inc.
is it safe to run the furnace with pressure switch bypassed until I can get a new one?
