Check the thermostat setting on back for electric heat. sounds like it is on gas heat. the fan should turn on right away if it is electric or heat pump.

SOURCE: air conditioning runs all the time

I assume this is a manufactured home, this is probably a two transformer system, either your contactor is welded in the on positon or wyou have control wiring issues, (could be the thermostat)

Troubleshooting and Repair
Furnaces with electronic ignition systems may be much more efficient than their early counterparts, but they do it largely through electronics. However, there are still some troubleshooting you can do but fixing the problems can involve replacement of parts more so than repair or adjustment. PROBLEM: Furnace burner will not ignite
Possible Solution

  • With a Hot Surface Ignition (HSI) system, if a gas hissing sound is heard for about 7-10 seconds and the burners do not ignite, the furnace will go into lockout mode.
  • To reset turn the furnace power switch off and back on and try again. The switch is probably located on the side of the furnace. A reset button may also be found on the solid state controller. If resetting fails again, proceed as follows.
  • Turn off power and gas to the furnace
  • Remove and check hot surface igniter being careful not to touch the heat element. If it is cracked or damaged, replace the igniter.
      PROBLEM: Furnace comes on for 7-10 seconds then turns off Possible Solution:
      • Turn off power and gas to the furnace
      • Remove flame sensor from its bracket. Lightly clean the surface with fine emery cloth and replace.
      • The problem may also lie in a bad ground or the the black and white wires being reversed (reversed polarity) at the junction box or outlet powering the furnace.
      • The electronic ignition control module must ensure current flow through the flame sensor to ground and if the polarity is reversed in the circuit there is no voltage potential and the flame sensor does not work and closes the gas valve.
      • If the black and white wires are connected correctly and the flame still drops out, then the issue may be a bad ground. Using a volt-ohm meter, measure between the white wire and the ground wire to be sure you have no voltage.

Coleman Evcon EB15B heat doesnt stop when it reaches the temp set on the themostat just gets hotter and hotter until I shut it of at the circuit breaker


Thermostat not doing it's job.
Probably the contacts on the thermostat are stuck together, Caused by arcing each time it opens.
If you are up to it.... clean the contacts or replace thermostat,

Cheers

Coleman Evcon Eb15b we replaced thermostat last night so that wasn't it when. Put in auto for heat u can hear a click. See where and feel it heating up tgen u hear. Another. Click and nothing even the heat...


if you turn on heat and no fan comes on, the electric will over heat and trigger high limit switch. the switch either self resets after it cools for a while or needs manual reset. read directions on thermostat for electric heat. energizes fan at same time as heat on calling from stat.

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.

My central electric furnace eb15b heats up up but the blowers not turning on?


Most likely it is the sequencer that is bad. Try turning the fan on with the thermostat. If it runs in "on" and not in "auto", most likely it is a bad sequencer.

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.

My coleman central electric furnace only blows cool air


The AC unit outdoors must be running and rejecting heat by its air flowing through it the 2 copper lines are the refrigerant lines, the fatter one should be "beer can cold" if not its low on refrigerant or not running.
