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.

Why is water coming out of my furnace exhaust pipe?


When natural gas or propane burns, water vapor is given off within the flu gasses so a bit of condensation in, off and around the flu discharge is quite normal. If it is a high efficiency furnace with the pvc flu pipe, they must be pitched properly BACK TO the furnace so the moisture will drain backwards and out a drain tap at the bottom of the riser. That style of furnace will have TWO drains...one up high for the air conditioner coil and one about 16" up from the bottom of the furnace off of the 'condensing coil' that the flue gasses pass through to extract a much greater amount of heat from the burned gas.

Many flu pipes are installed incorrectly which causes water to drip outside instead of back to the furnace and this usually results in huge icicles hanging off of them in the winter and eventually the partial blockage causes the flu's pressure switch to open.

If you have regular galvanized flu pipe, you have less than a 90% high efficiency furnace and the resultant flu gas temperature is much higher with a much greater quantity of water vapor in it. A little condensation is somewhat normal on the top of the flu cap as the hot moisture laden vapor comes in contact with the cold and dry outside air. If the moisture is all over the galvanized flu pipe in the basement, you are possibly venting into an oversized and unlined masonry chimney. IF that's the case, the chimney should really be lined with a flexible liner and properly connected to the furnace and water heater (if gas fired) with the proper connections and configuration.

Tip

2 Stage Furnaces More Comfort and Save Money


Two stage hot air furnaces can save you money and make your high efficiency furnace even better. With your furnace running at low fire instead of cranking up to the highest heating output in mild weather you can be more comfortable while saving money.

Many people think that they are getting the best they can get by buying a high efficiency single stage furnace. What they often don’t realize is that they could do better yet and for a few dollars more have a high efficiency 2 stage furnace that could keep them much more comfortable.


There are 2 stage hot air furnaces that are now available that will only run at half fire if the full fire is not needed. With a two stage furnace in mild weather when only a little bit of heat is needed, the furnace will have longer run times on low fire. This will keep you room temperatures from getting too hot before the thermostat reacts and shuts the furnace off again. This will help to keep your temperatures from overshooting the set point and help to keep your home much more comfortable.

Many of these two stage furnaces also have variable speed blowers that run at a lower speed when heating on low fire. This will also help to save money on your electric bill, because these blowers use very little electric when running at these low speeds. Air noise from the blower running at a high speed is also reduced.

If you are thinking of replacing or installing a hot air furnace, make sure that you ask your contractor to give you a price on installing a two stage furnace. The price difference probably will not be much higher than a high efficiency single stage furnace. However the comfort of the two stage furnace coupled with the electric savings will make the extra money well worth it.

Why does my waste oil heater burner shut off after about 15-20 seconds of running?


Depends on if you have to manually reset the primary controller. You may have a bad CAD cell, primary controller, backdraft of exhaust, or high temperature limit tripping due to overheating from either a loose belt, bad blower motor or capacitor. If there is a fuel filter, that may also be somewhat stopped up.

Furnace glow coil lights then goes out before gas


Need to know what make, model etc. High or medium efficiency???. If the exhaust blower is not spinning to pressurize the burner chamber it will not allow the gas to turn on.

Hi,

Sounds like the blower motor is bad and then the unit is kicking off on high limit....

f this is a metal vent 80% furnace,Turn Furnace off
and remove the vent that connects to furnace and see if it is plugged.

If this is a High Eff furnace witrh pvc vents for
exhaust and intake air make sure they are not plugged on the outside.

Turn thermostat all the way up,turn furnace off and
wait a few minutes.This should reset any control
board fualt.

Turn the furnace back on, if you have a glow coil
ignitor it should glow red and then the burners should
ignite. If this doesnt happen then:

On High Eff Furnace if the glow coil does not glow red, remove the combustion door to the burners,
turn furnace back on, if the glow coil glows and
burner ignites, you have an obstruction in the intake
air side. If it still does nothing then:

Use caution and remove the exhaust vent from furnace, start furnace, if furnace runs then you
have a problem with the vent system

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..

My heater turns on the gas starts but then it shuts down


Try to locate the red and white wires either behind your thermostat or on the furnace itself. Jump them out and see if the furnace stays on. If you do it at the furnace you will need to hold the door switch down. If it runs fine, you have found your problem (the thermostat) if it goes out again, the furnace will display a number of blinks on the circuit board. Look on the reverse side of the furnace access door and there should be an Error Code chart to get you started figuring where to look next.
