Question about Carrier Weathermaker 8000 Gas Furnace 125k Btu

2 Answers

My carrier weathermaker 8000 will not blow gas when the igniter lights up

The fan runs but the furnace won't release gas when the igniter glows. it glows three times and the furnace shuts down. i have cleaned the tubes, the end of the flame sensor and vacuumed out the dust and debris around the tubes and the panel area. i have also shut down the system as per the panel instructions at least a dozen times. i need help badly.

SOURCE: carrier furnace weathermaker 8000

. Several times of recyling power normally brings the furnance up. Though the failure code has always been 31, there are several different behaviour when the blower starts after reset :
a. blower simply creases.
b. there is an attempt to start the heating unit (I hear the high pitch noises), then everything stops.
c. there is an attempt to start the heating unit (I hear the high pitch noises), once I see the orange glow from the coil, normally the gas is lit up and the unit starts working.

SOURCE: Flame sensor dirty

Sandpaper lightly scrubbed over the sensor tip to remove any contamination.

Sometimes cleaning is not enough and the sensor must be replaced.

If you're sure the igniter is good and the controller is sending voltage to gas valve to open, but not to the igniter then, yes, the controller is bad. The only way to know for sure is to remove the igniter's molded plug from the board and test voltage directly at the board. You should get about 100-120 vac to the igniter.

SOURCE: carrier infinity 80 won't heat

does your burner flame up and then go put two or three times if so
all you have to do is take out the burner and clean all the soot out of it and then wipe off the sensor

Furnace wont run


First of all when you flip the switch, it goes thru a startup sequence. THEN it turns on the Igniter (notice the red glow). Then the gas turns on.

Now at this point check the idiot light and it should be giving you a code of 34. That 34 (3 shorts 4 longs) says that there was a problem igniting the furnace. After it cycles thru at least 4 times and fails to ignite all the blowers, then is when you get a code 14 (1 short 3 longs)

NOTICE what's happening with ALL the burner Tubes each time it attempts to ignite. If only one or two are running....then this is your problem.
To fix all you do is take out the burner Tubes, look for debris, blow them out (blow from the front where all the jets are), and replace them in sequence from left to right (the tabs overlap).

Carrier Weathermaker gas 8000 will not ignite


Your hot surface igniter may be bad. It may be cracked which would prevent it from starting the burner flame.
