Cant find wireing diagram for carrier 585ejw30050ca

Gas valve replacement ef32cw183 w-r is configured differently from orig valve thougths on this 5 wire setup ? are the 2/3 terminals common more details 2/3 goes to rectifier bridge and piolot coil 5 is the other end of circut 1/3 main burner coil 4/5 pressure switch old valve had single internal solenoid 3 wire proven piolet spark igniter setup

    p.s gas control sol for piolet clicks when w and heat connected gas flow at valve but none at piolet outlet or piolet outlet check port tried adjusting piolet level gas valve is on position perhaps fautly new vavle ?

    have the valve wireing diagram but not the heater will check for output voltages from the heater. can you embelish on how the pressure switch (insde the gas valve) functions ? this is a redundant type valve 4 .250 connections 1 .200 connection on the old valve the smaller wire was on a common coil winding new valve is a w-r ef32cw183 or in newer valve number 36e 304 (type 24) redundant fast open 24volt white rodgers inst sheet 99ta503033e im thinking that you are correct and there is a safety holding up the gas flow since i get spark and the piolet sol clicks when i call for heat wth / red connected

    orig wire harness was as follows piolet green to mgv sol term and spark ignitor yellow from piolet to mgv sol term changes to brown to temp switch
    black wire (common to a lot of terminals) pr swithc to mgv sol term slos to ign box and 24volt xfmr other side of pressure switch goes to 24 volt xfmr (other leg) brown pr switch in old valve had small (very small) wires going to a resistor and a sort of stopper that was attached to a spring on the inside of the gas inlet to the mgv (main gas valve) in summary 5 wire valve has terminals in different locations than the replacement valve

    gas valve working ok now but excessive current draw thru thermostat opens on anticipation after 30 seconds ??

  • waltcoolkat Jan 10, 2009

    thx rayname you were on the right track turns our i had a coil common and power feed reversed changed them to correct terminals and its working but still have problem remaining refered to above excessive thermostat amp draw will try checking for control coil shorts

If you have a volt/ohm meter you can unplug all the wires to the valve set the meter to ohms and check to see across each terminal which have measurable resistance these should be the coil, usually the diagram is on the panel door i guess this is not the case so you will probably have to see which wires have voltage when your tstat is calling for heat also you need to make sure there are no other safety holding this circuit out let me know how you make out

Carrier furnace burners will not light.if i blow at the burners it will light.I think maybe bad gas valve or not enough pressure

this sounds exactly like the problem. I replaced a gas valve yesterday in a Goodman furnace that had the same symptoms. I would check it or have it checked with a manometer before you replace the valve. If your inlet pressure is right and you cant get enough pressure by turning the adjustment screw clockwise, it is bad. LP should have @11-13inches of water column coming into the vavle and an outlet pressure of 7 inches of water column. Natural gas should have @5-7 inches coming in and an outlet pressure of 3.5 inches of water column

Carrier Gas Furnace runs fine randomly stops blowing LEDs flash

That blinking light may be the diagnostic light. Count the blinks next time it fails. Carrier units will have two different blinks depicting the error code such as one blink followed by a pause than 3 blinks giving you an error code of 13. Then look at the wiring diagram, it will have an error code chart telling you where to start with your diagnosis. You already know that if you remove the cover it erases the error code, so look thru the small window first.

Need wiring diagram for a carrier 383kav11048075? im replacing the icm281 control module. gas furnace

There should be a wiring diagram on the panel of the furnace. In the box of the icm 281 is step by step instructions.

Maybe this will help

Take notes on your low voltage wires from the thermostat and condenser. W Y R C G. Write down what color wires go to above terminals.

On your high voltage wiring,
Take the black wire from the transformer and put it on PR-1.
Take the white wire from the transformer and put it on PR-2
Take the black power wire from the panel interlock switch and connect it to L1
Take the white neutral power wire and connect it to L2
Take the black fan motor wire and connect it to HI
Take the red fan motor wire and connect it to LO
Take the white fan motor wire and connect it to COM
Then reconnect your low voltage terminal wires to W Y R C G.

Thats it.

Orange or O terminal on Tstat energizes valve in colling cycle. Go to outside unit jumper red to orange and see if Reversing valve energizes. If it does . Problem inside possible Tstat. You shoulf here the valve click. Have someone inside switch from off to cool you should here valve. Rusty

Carrier Heating furnace

either the gas at the outside valve is off, or the gas valve at the furnace may be off, or the switch on top of the gas valve in the furace may be off. if they are all on, then you may not be getting a call for heat from the stat to the furnace control board. check to see if you are getting a 24 volt signal from the stat to the w terminal and common terminal on the furnace board. if you are then check to see if the voltage is arriving as 24 volts to the wires at the gas valve itself . if it is then the gas valve is possibly bad. if it is not then the board is possibly bad.look for loose or broken connections on the low voltage wiring. most unusual that the board does everything else but send power to the gas valve. you need to zero in on the valve i think and start by turning off power and that should restart the sequence of operation and you can observe it step by step . if you are not getting a call for heat then the stat may be bad be sure you are in heat , fan in auto and temp pushed up to max. if no 24 volts is sent to furnace board white and common low voltage board then stat is bad. remove it if you think its faulty and jumper the white and red wires together on the subbase. that duplicates what the stat normally does. if the furnace lights its the stat. having said that i realize the stat has to be sending a heat signal or the other stuff would'nt start. so..... back to the furnace board. check that 24 volts in from stat and 24 out to valve and that will put you on your problem item. good luck

Need to stat brand name of equipment, differant manufacturers use different codes. There should be a listing on the front panel or on the inside of blower door with the wiring diagram.
