Coleman Home Electric Furnace Eb15b/Eb15d Questions & Answers
Blower fan continually runs
It may be but the fan control may be set to turn off at to high a temp, or theres a short between ;r; and g at the stat or furnace or sequencer, IF it runs through it. A limit or rollout switch may have failed but this will keep the unit from firering. Check for a manual blower switch that may be on. At stat it should be at auto and alsso at the fan control. A stuck relay is always possible,
To much condasation leacking on floor wy is it leacking
the condensate catch pan may have a problem like cracked or something but more likely drain line is plugged up. if you are not plumbing or mechanically skilled you should probably get a technician to fix it. if it is only plugged it will be a service call expense, if you mess it up trying to fix it it will be much more.
Heat element continues after t-stat satisfied.
Sounds like the heating element has broken in two and is shorted to ground. even with only 110 to one side of the element and if the element burns in two and fall against the side of the frame it will complete the circuit and begin to heat up. Make sure you shut the power off to the furnace and then pull the heating element assembly and examine the elements to see if any are broken and shorted to the frame.
Furnace kicks on then shuts off
Coleman furnaces us a temperature delay with a temperature on around 130F to 150F and off around 110F.
If the inrush of cold air cools the delay below the off temperature the fan will go off until the heater heats it up to the on temperature.
Blower not shuting off properly
The blower is controlled in col by the fan relay, in heat by the temperature delay, if you tap the delay it will shut off usually, just replace it its not expensive.
Fan won't blow on ac, but works on furnace
The fans heat speed is low speed and the cool speed is high speed. High speed is controlled by the fan relay normally open switch, the low speed is controlled by the temperature delay or time delay.
see diagram
Ac not cold
The AC unit has 2 copper pipes, 1 is larger, this one should be "beer can cold" in AC mode, if not its low on refrigerant or not running.
Blower motor will not come on
If the blower motor has correct voltage and not running it can be a capacitor, its about $5 to try it, otherwise a new fan motor is required.
No fan when ac kicks on Ihave a eb15b funace with a coleman ac
The heat will normally use a low speed on the fan, & the AC along with the fan switch on the thermostat will use the high speed. The thermostat turns that high speed on when there is a call for cooling & is the same switch if you were to manually turn the fan from auto to on. Try turning the fan on @ the thermostat. If it works, then replace your thermostat. If it doesn't, it could be a bad fan speed, a bad fan relay on a control board or external relay, or a loose or broken green thermostat wire.
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.
Heating elements keep coming on and off after blower turns off
Yes your sequencer is the switch to energize the elements & sometime the low speed on the blower motor. It completes the 240 volts going to the elements. The sequencer turns the elements on in stages as well as the blower, & most sequencers have numbers on the side to tell what thermal disk turns on first. The blower, & one element should be wired on the 1 & 2 terminals (this turns on first when the sequencer coil is energized & shuts off last when the coil is de-energized). If any of the thermal discs are stuck closed, this will constantly energize the element on that switch.
Convert coleman eb15b to natural gas unit
Sorry there is no way to convert it to a gas unit.. The only way is to replace the furnace with a natural gas unit. You will need a gas line ran to it and a Flue. and then room to fit everything in that space.
