SOURCE: M heater comes on and gets hot but fan doesn't

Usualy the fan absorb dust and dirt which located on its axis and support ball bearing and this making it more hard to rotate so some times rotate and some times is not. However if you are capapble you desasemeble the motor and clean the shaft axis and lubricated the ball bearings, if its is dificult for you, you can use a lubrican oil in between shaft axis and bearings this can help it run better.
The final solution is to replace the fan motor

Furnace fan will not stop running till you pull out fuse


Most likely the fan relay is defective or the electric heater is defective. If the fan will not turn off, the cause is generally the electric heat is being back feed from a defective heat strip., Recommend call pro. If so inclined, remove power, breaker etc find 1/4or 5/16 driver and Remove panel from the ah. Look for the fan and follow the wires back to the relay( this is usually black,for high speed, blue for.med and red for low ) Follow the fan speed tap to the relay. If the relay is burnt or looks defective replace this part. If no defect is obvious remove the wire from the NC (normally closed) connection. Plug the power and check to see if the fan starts with out command. If the fan starts it definitely the relay. Note the wire removed from NC might be hot check with meter if it is and the electric heat is signalling the fan to run and most likely source of defect is the heat sequencers, (switch relays for high voltages) replace this part

I have a evcon EB12B where is the reset button. The blower stays on even if heater is turned off at thermostat. I have to turn off in breaker box


This may need the furnace technician to repair.

I can locate the manual for your heater and the parts list but I cannot locate any reset button.

Blowers that run all the time have either a stuck fan relay or depending on age, have either a defective "fan control and limit switch" or a breaker that operates the fan. When the furnace ignites the fan waits until the air get hot before it blows. When the heat goes off, the fan continues to run until the furnace is cool.

You probably can replace the parts yourself but please make sure it runs safely. The making sure is what the furnace tech will do.

Electric furnace fan works heater does not


coil could be broken. open the cover hold the door switch and look to see if the coil glows when the heater is turned on if not turn off the power then remove the coil then turn on the power and check the voltage you should get 210V A/C on a meeter if you do or yo can do this firs, check for continuity on the coil if you get continuity then check for voltage. if no voltage check the breakers or check the breakers first the electric heater needs two breaker if one is tripped you could have a blower and no heat.

Electric furnace will not turn off


Your sequencer is stuck. A sequencer uses a small coil to warm up the switch so that it will turn the electrical elements on one at a time instead of all at once. If they all come on at once the amp draw would throw the breaker. It is also desired to have warm air come out of the vents when the fan comes on. So how do they do it? With a sequencer:
themobilian_3091.jpg
A sequencer can have up to 4 stacks depending on the amount of coils are in the heater. Each coil on average has a value of 5000 watts. So what ya want to do is turn on a coil then after 30 seconds another coil then after 30 more seconds the fan and maybe another coil depending on your furnace size.
So in your case what is wrong? The sequencer bimetal disc inside it is jammed in the on position and therefore the heater stays on until you tun the breaker off. Replace the sequencer and party on!

Heil heater starts/stops before reaching temp


is installed in a vertical up flow or horizontal position , if in horz position you could have a bad or miss positioned roll out switch this is a thermal switch positioned toward the burner edge that if the flame rolls out of burner area trips and then resets as it cools allowing the furnace to re-start until it reaches temperature , something to check .
