carrier 9200 wont light
 
i have a carrier 9200 weathermaker.the drain recently plugged and backed water into a black box behind the blower. i cleaned the drain pipe,which was restricted.now the blower run for around 90 seconds and there is not ignition.if i blow into to pressure switch and hold pressure it clicks and lights and will run as long as i can blow.could this be a failed pressure switch,and where can i get one.thanks

Hi chizler40

When the inducer starts if you are hearing water slosh it will not allow the inducer to run up to speed. If the inducer does not run up to speed the pressure switch will not make or hold. You will need to blow the condensate trap out and may need to remove the hoses off of the collector and the inducer drains. You will usually see a build up in the ports. Clean all of these components and see if this gets you going. You can use a mild solution of bleach and water, this will clean all the algae and build up out. But before attempting any repairs, unplug or shut the power off to the furnace. If you need any further help, one of us will be here.

Good luck
Rusty

thanks for the quick reply Rusty.i cleaned all the pipes drains and hoses but it still the same. the holes were definitly plugged.i also noticed a code 13 does this mean anything. it goes to a solid glow when i blow on the pressure switch hose.

Hi chizler40

If you turn your front panel around, there will be a chart with numbers to the right side and definitions to the left. Or it could be vise versa, not all models were the same until the later years. The code you are getting is a limit trip. If you look up on the side of the burner box you will see two red wires going to a black thing about the diameter of a dime. Between the two wires will be a button. Push straight in on this button until it snaps. At this point the code should go away and the furnace will operate. If it doesn't let me know and we will go to the next step.

Good luck
Rusty

thanks again
 
it was the pressure switch that the small rubber hoses go to.

Hi chizler40

Its nice you got it going. By the solution to the problem being the pressure switch, the code you were reading was actually a 31. The first digit in a Carrier code is always the fast flash and the second is the slow. This will help you with any future problems.

Good luck
Rusty
