SOURCE: pressure switch stuck open

It most likely is not stuck..... It is just doing its job. You "most likely" have over problems. To "properly" diagnos this problem you will need a manehelic gauge. You can have a wide variety of problems from as simple as a blocked or disconnected vacum hose to a lifetheatening problem.... a blocked flue pipe or a bad heatexchanger.
BE CAREFULL
GOOD LUCK!

SOURCE: Need to find the pressure switch on my goodman furnace

It's mounted onto the gas valve. It will be a button or lever that you have to push in or down, depending on the style.

SOURCE: I have a Goodman GDS80904BNA. I'm getting 3

These furnaces have notoriously bad circuit boards. The light will give you a diagnostic code and after you have replaced every component there it still will not work right. Need to know more specifically the order of events happening. the blower should turn on (draft blower) then after a second a click and you will see the ignitor glow bright orange then click the gas valve opens and the burners light. most of the time this will all happen and then the flame in all burners will go out and it will attempt the whole process over. if this is the case turn power off and then remove the circuit board from the 4 retainer clips and look at the back 9 times out of 10 the board will be dark brown in one or two spots large spots at that. time to replace the circuit board. They have updated the board and it is being made by a different company now. Take a picture of the board before you remove any wires so you can replace the wires in the proper location.

I have installed a wood burning furnace and was hoping to run the blower on my goodman gms80703an and thermostat without having to ignight the gas furnace


If I am understanding you correctly, you are just wanting to circulate the air with your gas furnace and heat the air with your wood burning stove. You should be able to set the fan switch to the ON position and leave the heat/cool/off switch in the off position.

Heater does not come on gms80703an


There are too many reasons for this to happen so we would have to narrow it down. The sequence of operation on a Goodman furnace is usually:
1: Inducer draft motor comes on
2: Hot surface ignitor comes on and glows
3: Gas valve opens, lights burners
4: Flame sensor detects flames
5: Blower comes on

If the inducer motor never came on, then you start looking at power to the unit, thermostat issues, or inducer motor issues. Just a few places to start. Hope this helps!

MY Goodman furnace mdl #GMS80703AN would not come on. Diagnostic lite flashed in threes. I called Installer who instructed me to stick a small wire or other object carefully into hose connection from...


This code is for a pressure switch failure. Do not stick anything into the pressure switch or blow into it. Either will damage it. You may however do as your technician suggested and clean the inducer motor port as well as the hose. If this does not fix it, begin inspecting the flu for blockage and make sure there is enough combustion air supplied to the room for combustion to be sustained. If all of this checks out ok, You can use a Ohms meter to check the continuity on the pressure switch. If this is ok you may have a gas pressure problem. Do not attempt to adjust the gas pressure if you are not certified to do so because the gas valve can be damage in the process not to mention the risk of explosion. Good Luck!

I have a goodman gcs90703bxa flashes 3 times blowed in the pressure hoses went from 3-2 flashes what could be wrong?>


flash 3 is a blocked pressure hose. the switch is open. flash 2 is the pressure switch stucked closed. if you applied pressure to the swich you may have damaged it . It typically clogs on the Induced draft motor housing on the bard fitting that the hose from the pressure switch connects to. sometimes if you take a paper clip and **** it out. but never apply pressure or tools to the switch.

Furnace code light flashes 3 times /pressure switch stuck open


Check the intake and exhaust plumbing for any obstructions. I had same issue, turned out to be ice in the air intake plumbing on outside of house. This may be the problem. The pressure switch can be tested by pulling hose from purge motor that goes to switch and applying a small amount of suction. The switch should make a clicking sound.
