    INTERTHERM Gas Furnace Model # MGHB090AAPQ-1. The furnace has been working fine until recently. When the fan finishes blowing the hot air, the motor at the bottom of the exaust chimney stays running.

    Thank-You. How do I go about replacing the thermal sensor switch.

  • kaadahewlett Dec 30, 2008

    Thank-you. It seems like my air filter may have been overdue to be replaced. This may have been causing wrong signals to go to the Thermal Sensor.
    Your solution was very helpful.
    Thank-You and a Happy New Year.

Hello and welcome to FixYa!,

This problem is caused by a defective Heating Coil or ThermoStat Sensor, these may need to be replaced as they might have become defective or broken.

This might be the solution you are looking for - hope it is your FixYa!

There should be a small thermal switch (heat sensing component) near the heating coil. If this switch is defective, the fan will stay running since it still "thinks" the coils are hot. Replace the thermal sensor, and it should be fine.

Some connections are crossed up still supplying a small amount of power to the motor.

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.

My Lenox EL296uhv furnace quit running has error 227 & 228 code.


Your induction blower motor makes vacuum as it blows out the exhaust. these code are saying that there is no vacuum..It is probably caused by your exhaust being blocked by something. Maybe snow or ice build up due to cold temp. Try a hair dryer to heat up exhaust pvc pipe melt ice in pipe. CAREFULL do not get it so hot it melts.

The blower on my Dayton furnace runs but there is no flame/ignition. Just blows unheated air. It continues to run regardless of whether the thermostat is calling for heat or not. Anyone have any ideas?


When the blower motor run all the time, that mean you have a safety limit tripped. One of the limit is located on top of the burner, to reset that all you have to do is press down on a little tap that sticking up in the middle of the switch. The second switch is located at the flute pipe, to reset the switch is the same procedure. The third limit switch is located on the heat exchanger box itself, this one cannot be reset, you will need an ohm meter to check for contunuity. Set meter to ohm function, if the meter read nothing then the switch is bad. Good luck.

Furnace will not blow hot or shut off


The furnace has a fault check the furnace compartment for a flash code and check it with the code chart on the furnace door. Turning the power off to the furnace and turning it back on will reset the fault but it may happen again till you verify the fault and fix it.

The floor vents in our house are blowing cold air instead of hot. What can we do to fix it? What would be causing this?


If the furnace is running and the registers are blowing cold air you have a problem with the furnace. Check to be sure the pilot lite is lite if this is a standing pilot, if not check to see if there is a flash code in the site hole in the bottom blower door of the furnace. Be sure the thermostat is set to heat and turned up.

I love the functionally and efficiency of my Rinnai water heater, however, we smell funes in our bedroom after hot water usage .. our bedroom is right above the area in the basement where the water heater...


The unit is a completly sealed unit. which uses combustion air from the outside & exausts to the outside. check for leaks on the exaust pipe with soapy water while running. if you see bubbles , theres the leak. if not, the exaut may be getting sucked back into the house through a window or other opening to close to the exaust.

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..

Furnace not blowing hot air


Check your flu pipe and make sure there is no obstruction in the entire pipe. Sometimes the exhaust fan for the flu will not come on because the safety will not allow it to and it will also cause the fan to run, but not the burners to engage ignition.
Hope that helps.
God Bless.
