Build some kind of barrier outside so the wind doesn't hit the vent. A piece of plywood before it or a big box around the vent. There is a pressure switch that the wind is messing with. It is a safety and necessary for the furnace to run properly.

It's the pressure switch on the unit. Make sure that the pressure switch doesn't have debris in it that keeps it from operating smoothly. Take the tubing off from the inducer side and breath in and blow out lightly while listening for a clicking noise. If that doesn't work then I would recommend replacing it. That should solve the issue.

I have Rheem Pvw50, 50 gallon water heater installed at home. For the past few days, there is a noise coming out of blower motor. What could be the reason?


Your water heat is at an age that I would recommend replacing the whole unit. That one cannot be too efficient and most likely has sediment built up on the bottom of it pretty bad.

Is 32c a normal temp for an exhaust on a force air high efficiency house furnace? This is the air temp that goes outside after heating the plenum. Is there a lot of heat going up the "chimney"??


Any furnace providing heat where it should and has little to no heat from its exhaust is doing a GREAT job ;-)

Our high efficiency gas furnace was installed with a PVC pipe as a 'chimney' which bothered me to no end until I found the surface temp of that plastic pipe only barely warm to the touch- that is a home run!

This is possible, however it is possible they are missing something simple. I hope you can follow along.
1) Is this a Sealed Combustion Furnace, meaning you cannot get to the burners even after you remove the Door Panels?

2) If yes, is this furnace vented with pvc/plastic piping?
3) If yes, do both pipes go outside?
4) If yes then try this.

1) Turn the main power off to the furnace
2) Remove the Door Panel to the burner section.
3) Turn Furnace back and turn the thermostat all the way up.
4)Look into the burner compartment and tell me if the igniter glows red. If it does and the goes out with the burners not coming on.

5) If you feel comfortable or know of someone that is.
6) Turn the furnace off, remove the panel that conceals the burner compartment.

7) Turn the furnace on, if the igniter glows red and the burners ignite. Your problem is in the venting system. Most likely the intake pipe if it goes outside. It could be plugged or something is blocking it. If the burners do not ignite the next thing to make sure that is happening is that the Exhaust blower is operating and you can feel air outside where the pipe terminates. If you it is but no very strong, then your problem could be the inducer motor or to small of vent pipe.

If you could, send me some information about how it starts up
1) Main blower may come on and shut off, make sure the blower runs in on position 1st then back to Auto position. If it does not, you have another problem.

2) The Exhaust blower should come on next
3) About 17secs. later the igniter should glow red.
4) You will here the gas valve make a click
5) The Burners will ignite
6) The flame sensor rod on the far left hand side of the burner will keep the burner lit. If it is dirty the burners will shutdown.
7)About 90secs. later the main blower will come on.

My gas goodman heater will not ignite.


It is probably not the glow coil, if this is a 80% regular
furnace, Make sure the induced draft blower is working. I once went to a house where I came across
this problem, the only difference is that it would acutually start and then shut off. I took the vent apart
at the furnace and found a bird that was preety cooked.

If this is a90% High Eff. furnace, make sure the pvc
vents are not plugged. To troubleshoot the intake
Vent. Remove the combustion plate and then turn
the unit on, if it runs you have a problem with the
intake vent.

You could temp. remove the exhaust vent and then turn on the power if it runs then your exhaust vent
is probably plugged. You could go outside and make sure the vents are free.

Make sure you have gas available, these are the most commom issues that could solve your problem

Heat not coming on carrier gas pack code 31


code 31 indicates pressure switch did not close or reopened during the heat cycle....1st thing to check is the inducer motor,,this is a small motor that turns a small blower wheel that draws the exhaust gases through the furnace and blows them into the vent pipe....1st locate the inducer assembly,,most easily identified by the small plastic fan blade that cools the inducer motor as it runs..1st turn off tstat and turn off furnace power switch..then turn on furnace switch,then set tstat to heat,set the temp above room temp by 5 degrees...remove the furnace front cover,locate the inducer motor,,if it isnt turning,but is warm or hot after a minute or so,likely the inducer motor is bad..if it isnt turning and isnt warm after 1 minute,then likely the main control board is bad,,not turning the inducer motor when it should,,,,,if the inducer motor is running,,then the pressure switch isnt closing,, could be a bad pressure switch but more likely there is a problem with the venting...some possible problems that would cause the pressure switch not to close in an 80% eff furnace [metal vent pipe] are: [1] a blockage in the vent pipe,base of chimney,dead bird at the furnace where vent connects to furnace or down inside the inducer assy,accessed by removing vent pipe from furnace....if all clear the chimney could be blocked up inside,,is the draft good when vent is removed from base of chimney?..if furnace is a 90%+ type [pvc plastic vent pipe],,then check the intake pipe at the furnace by removing it where it attaches to top of furnace..is the intake clogged with anything?..then check the intake and exhaust pipes outside for blockages,,including ice/frost/snow at the exhaust pipe outlet..
