Maybe youhave a pinched thermostat wire. If the room air blower is blowing, At the control board remove the wire located on the G terminal. What keeps this blower turning is a connection between the R and G terminals. The heat is caused by a connection between the R and W terminals. So if you disconnect the R wire and the unit turns off, you do have a short in the thermostat wire. If it keeps going, you have a bad board.

I am guessing its just the fan that keeps running? If so you have a sticking fan relay It is part of the control board. You would need to repace it.

Try tapping on the control board on the little black box and see if it shuts off.

    I did not see yo had replaced the board.

    Try undoing the thermostat wires from the furnace Does it still run? If not you have a short in the thermostat wiring in the wall somewhere.

    If it still runs then you may have a bad limit switch somewhere and the fan will run Is there a flashing light check the number of flashes and there will be a code somewhere on your panels there should be a legend for the code.

What to do when my hot water heater smells like rotten eggs

This is for electric water heater:

Flip the water heater breaker off in electric main.
Shut off water to the heater. If there is no valve on the cold supply side, then you will need to kill the water to the whole house.
Attach a water hose to the bottom outlet.
run the hose outside so the end is lower than the bottom of the heater.
open the valve on the bottom outlet.
The water in the heater will start trickling out and bringing sediment with it.
Once the water stops flowing, turn the water back on. This will refill the water heater, flush more sediment, and rinse the tank out. Allow it to run until the water runs clear, if stained.
Close the drain valve, disconnect hose, turn power back on.
If the problem was due to deposits in the water heater, this flushing should remove the offending materials and odors. Good luck!

For Gas, do the same thing except turn the gas down to pilot only or vacation mode while flushing instead of shutting off a breaker which the gas heater will not have.

I have a Lennox Gas Heater that will work for a while and then stop working (or fail to turn on when it cools down in the house). I changed the thermostat in the hallway about 6 months ago so I don't think...

Hi, i've found out that the flame sensor (rod that sits within the flame) is fouled with carbon on the surface. I believe this shields the rod from proper heat detection and the sensor reports that there is no flame and to shut off the gas valve to avoid explosion. Once you pull out the rod and cleaned it with a wire brush, it should fix the problem whatsoever.

My lennox ecb29 electric heater heats but the blower does not come on and the breaker flips. . It will heat the room if I leave the fan on.


Okay... does the blower work or not???

Are you saying that if you turn on the blower first then it will run and the heater will then heat???

If that is the case then I would say that the blower is pulling too much current on the startup and then tripping the breaker if the heater is drawing also...

Try changing the motor capacitor...that may be bad or going bad...

Also you may just have a breaker that is going bad...

Try changing the breaker if changing the capacitor does not help...

My central heating unit is in the attic of my 2bd/2bth house. I don't know its age. It's a gas unit, but doesn't have a constant pilot flame. Rather, the pilot is ignited electronically. The problem is...

You don't mention make or model so here is my guess as to how to thinkout the trouble of what ever is in your attic.

For some reason, your heater is mis-firing. Normally, I would expect 3 to 5 such events at which time the heater goes out on safety. The heater knows it is on safety but you don't until it gets cold in your house. When you turn the power off, wait the 30 seconds, turn it back on, the heater no longer knows it is on safety (memory cleared) so it fires. Your heater continues to fire until ? at which time it starts counting again to 3 or some number. At the max mis-fire number - it goes out on safety again ... repeat - turn it off, wait 30 seconds, turn it back on - no memory and so forth.

Do you have a service contract or regular service man? Might be time to find one.

Thanks for your question at

Heater does not turn off

It could be, or it could be a wiring issue. Make sure that your wires are in the correct place (R or Rh and W), and that they are not touching each other. If you have the unit running, and you disconnect either of the wires, it should shut off. If it does not, then the problem is in the wiring. Hope this helps

Water heater problem (no leak on floor)

shut off the power to the hot water heater wait 5 to 15 min. If the noise stops it is the water heater eating up electricity. Turn it back on if noise starts again feel about 5 or so feet down the hot water line. If this line is hot you have a leak beyond the hot water heater. If you still hear it when the power is off to the water heater. next turn the water off on the cold water line at the water heater with the power off also Look at the water meter and see if the hand or wheel on the meter is moving and it should no be. Also think if the breaker to the hot water is off the electric meter should practically stop if no refrig oe anything else on. Have someone watch the electric meter and switch 1 breaker at a time leaving the one you just shut off in the off position until you cut them all off. Should the meter still be moving you have a main service cable shorting somewhere call the power company to advise you further if this is the problem.. Should just cutting the circuit breaker for the hot water heater stop the noise and down the hot water line is not hot then you are probably wasting power due to a thermostat or element inside the hot water heater.. Thank you j

Not knowing what kind of heater this is, I will assume that you are referring to a small plug in 110 volt room heater since you mention power outlet. Check the amp rating of your heater verses the breaker. Remember if it is a wall plug that there are other plugs on the same breaker. Breakers work two ways, as an over current (amps) and thermal protection (heat). It could range from too close of a current draw for the breaker and heating it up or a loose wiring connection at the breaker or wall plug. Loose could also be the problem for a central unit. After it runs a while place your finger on the front of the breaker to see if it feels hot, it should not get warm
