Having a problem with a weather maker 8000. It will not come on at all unless I shut down the switch on the side of the furnace. filters is clean. it will start to light then stop
. 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.
10 year old furnace started intermittent lock up with error code 31.
Careful investigation revealed intermittent inducer motor. It starts
but stops running or it won't start when heat is called for.
Took the control board out(HK42FZ004) and went through it. The problem found was cracked solder joint on two high Wattage resistors R34 and R33
(both 330 Ohms) had cracked solder joints on the PCB due to heat(?).
Reinforced the joints with silver solder. Now furnace is behaving normal again. Google search showed it is known problem mentioned in service bulletin. Going price for replacement board is ~200.00.
Hope this may be of some help for someone who has same furnace type.
(Carrier, Bryant, Payne brand uses same board I believe).

Check the flame sensor. its a little rod in front of one of the burners try to clean it with sand paper.
This happened to our wder maker 8000
the ignition sensor/ thermoresistor is broken get it serviced
this turning on and off is because the system checks if the gas is lit using the sensor, if it does not detect fir it will shut off to prevent explosion
Sand down the sensor, then it will work.
This is what happened to my WeatherMaker 8000 furnace.
I first hear a heat pump motor runs and gas lit through burner for a few seconds then shut off repeatly a few times. I also measure PL2 wires connect to Igniter which its' position on the second right burner counting from the right side when you face to furnace. Before gas lit into burner, the voltage is about 12 VAC until gas valve open to let gas into the burner then I measure at the PL2 wires which connect from PL2 to Igniter turned into 120VAC. Meaning that there is a power runs up to Igniter but Igniter does not have a connect , power was cutting off, then gas valve closed. I unscrewed the igniter and find out the the element from igniter broken. buy a igniter from dealer for the cost of 35 dollar plus my labour while I call for an service with the price of 300 plus. so far i am getting my furnace back working again. for this reason, i did research some things new about the flame sensor but i can not say i will be right for this. in case of the you can see a igniter turns light on, gas lit into burner and there is still problem of shutting off , then there could be possible a flame sensor malfunction. you can sand slightly off the carbon around the flame sensor. I think the flame sensor is picking up temperature and tells the cpu that so far there is a heat, then let cpu will let gas lit continuely into burner. it may possible that if there is a high heat exists, and flame sensor will tell the cpu shut off the gas valve and stops supply any more heat. if you are at this situation, you will smell a strong burn smell from the paint of the furnance, and it also tells me that the motor is now malfunction.
On this unit a code 31 usually is a high pressure switch or relay not closing. Use the diagram on the unit. Find pressure switch. There is a button in the center of the switch press it to reset. Also check the ignition module and flame sensor for burn out.
I think the running on power up is just a test mode for a service person.
Can this be fixed?

Weathermaker 8000 furnace lights, but shuts off almost immediately. Fan would not come on. At thermostat set fan to 'always' on mode. When burners lit, stayed on a little longer then furnace shut off including fan.
SAME PROBLEM NO HEAT WHEN THERO IS SET IT NEVER COME ON THE BLOWER WILL BLOW BUT NO HEAT CAN SEE RED BUT NO HEAT NEED HELP HOUSE IS VERY COLD
Same problem it will start up and when it is getting ready to kick on it will shut down and restart. I used the switch on the side a few times but it will not work any longer
furnice comes on runs for second kicks off repetes several times
I have a six burner Weathermaker 8000 the first three burners close to the gas valve light all the time the last three are intermitant .There is a sensor at the last burner that must be heated for the furnace to stay on or it will shut off. I cleaned the orfices with air and the pipe they sit on and it seemed to help a lot. Factory repair people had told me to buy a new furnace !!!
Same problem. What I did to fix it was to take off the sensor wire (this is done by un-clipping it and undoing 1 screw with a 1/4" nut driver) and clean it. Reposition it if necessary so the flame hits it but do not try to bend it as is will break easily.
weather maker 8000, fan would start but no light at all or as soon as it lit would shut off.
error code 34, ignition shut down,,where is the ignition sensor - to sand down?
error code 34, ignition shut down,,where is the ignition sensor - to sand down? i have the carrier 8000 furnace
I have a weather maker 8000. It will turn on but the burners will not come on to provide heat. There are lights that are flashing a code, 3long llights then three short. Help
same problem.... ignition will not come on with 3long and 3short on mother board in furnace..whats wrong and how do you fix?
My furnance will not start in the morning unless I turn the switch on the side of the furnance off and then on again.
Some times the furnace won't start unless I turn the kill switch on and off, then the igniter will come on then go off because the gas it seems won't come on, then the igniter will try again and the furnace will start. I don't think it is the thermestat as it is a new one.
The furnace is seven years old. I have already replaced motor.
Can anybody help? Thanks.

fan goes on, then flame lites for a few minutes then shuts down. i have to turn switch off then on & sometimes the 8000 furnace will cycle.
having a problem with a weather maker 8000. It will not come on at all
unless I shut down the switch on the side of the furnace. filters is
clean. it will start to light then stop
not blowing hot air
red light on, no flame
I have a Carrier Weathermaker 9300TS furnace and the filter (16X25 approx) says on the side to clean monthly. However it does not state how to clean it. How do I clean the filter?
carier furnace lite is on steady will not start turned breaker switch off for an hour hoping the cercirt board would restart but no luck
