I have already changed the heat sequencer&limit switches still no power to the sequencer and I'm getting 37voits @ thermostat


37 volts is way to much. Verify your transformer is set to proper voltage, 208 or 240. Then verify 24-27 volts on r terminal. Wire nut red green and white at stat to bypass tstat, then check low voltage to sequencer. If its anything other than 27 you have a bad wire or possibly a bad board. Not sure how your power gets to sequencer. Make sure you are testing sequencer on each side of coil, power and common, not power to cabinet. May have issue in common wire. Or try both P&C OR P TO cabinet

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.

Blower works no heat


Most electric furnaces use time delay relays called sequencers to turn the heating elements on and off. If your thermostat is calling for heat, the sequencer coil should get 24 volts and the contacts will close in a pre-determined order bringing on each element individually. If the sequencer coil is getting 24 volts and the elements are not heating, then one of the following issues is going on. 1. The sequencer contacts are not closing because it is defective. Therefore the heating element is never getting proper voltage (usually 208/230V) 2. The heating element may be broken. 3. The high temperature limit switch for the element may be open, not allowing proper voltage to the element, or 4. The element is not getting proper voltage because of a blown fuse, tripped breaker, or broken wire. I hope this helps!!!

Honeywell thermostat will not work when put on automatic


Depends on what type of heat you have...if it is electric, it could be your thermostat (some electric heaters use contactors & rely on the thermostat to switch the fan on). Heat pumps also use the thermostat to switch the fan on in heat & cool mode. Most electric furnaces use a sequencer to switch the low speed of the fan whenever there is a call for heat. Gas furnaces use either a fan/limit controller (if the unit is older) OR a circuit board based on time (after the thermostat calls for heat). SO depending on the type of system you have, it could be a bad sequencer, controller, relay, thermostat, or control board. Hope that helps.

Just replaced my digital therm, does the blue wire that was in C for the old therm go into "O", or "B" now? New therm is a Braeburn. Also do I have to reset something at the furnace?


Should go to C terminal. B and O are only used if you have a heat pump system. If you have a voltage tester you should have 24 volts between the wire connected to R and the blue wire (common)

My central heating is on lockout and the burner is with red light


A sampling of various codes on a furnace

Read one LED flash that stays on continuously to mean your furnace has no signal coming from the thermostat and will not operate. Turn the power off and check the thermostat for improper settings or connections.

Interpret one LED flash that blinks on and off to mean your furnace has locked out because it could not ignite after three tries, and must be reset. Interrupt power to your furnace for 20 seconds or lower the thermostat so your furnace does not try to heat, then reset the thermostat to the previous setting. After one hour of lockout, your furnace will automatically reset itself and try to operate as usual.

Decipher two LED flashes to mean the draft blower is not working, or your furnace has a short in the pressure switch circuit. Turn off the furnace power and repair a short or replace the pressure switch.


Read three LED flashes to mean your furnace has an open pressure switch circuit or it has an induced draft blower operating. Check the pressure switch hose of your furnace for blocks or an improper connection. Also, look for blockages in the flue, and tighten any loose wiring.

Translate four LED flashes to mean your furnace has a primary limit circuit open, possibly from loose wiring or blocked filters. Check and clean filters, tighten wiring and check the flue for blockages.

Interpret five LED flashes to mean your Goodman furnace senses a flame without a call for heat. This could be from a gas valve closing slowly or a burner flame lingering.



Read seven LED flashes as a warning of a low flame sense microamp signal. This could happen with a coated flame sensor or a lazy flame from poor gas pressure. Turn off the power and adjust the gas pressure according to the information on the rating plate.



See eight LED flashes as meaning an igniter circuit problem due to a bad igniter or an igniter connected improperly. Replace the bad igniter or check the ground wiring, making necessary corrections.



Decipher nine LED flashes to mean the high-stage pressure switch circuit will not close during a high-stage-induced draft blower operation. Your furnace may have a pinched or blocked pressure switch hose, a blocked flue or loose wiring.

Read continuous flashing on the LED to mean your furnace has a reversed polarity of 115 volts. Turn off the power and correct the wiring polarity after reviewing the wiring diagram.

Ruud air to air heatpump intertherm propane furnace honeywell th5220d non programable thermostate.fan on furnace will not turn off in aux.mode even though the furnace heat kicks on and off. thank you for...


Make sure fan relay is wired correctly (G) wire. Ensure the fan on therm is not on, it should be on Auto or off.

If your furnace is short cycling because it has to keep heating your home, the delay in the control board may be staying on to compensate for the exchangers getting hot. If it heats normally, then put your attention to your thermostat.

Set the heating system on aux heat only. Fan should not be on, if it does stay on after a heating cycle, see if the furnace is heating normally, and reaching temp as desired before the heat comes off. Then check the therm wiring, pull the face of the therm, disconnect green wire (fan) and try the heating again.

Air conditioner/furnace squirrel cage fan remains running when th


Ensure you don't have a short in your therm wires. Disconnect them, if the furnace continues to run, you have a lockout problem at your furnace. When the motor on the fan fails, it wont run. Check for led codes on the control board. If you don't have led codes, turn off the power to the furnace at the breaker, and watch the unit. If nothing happens, connect the thermostat. If nothing happens still call for heat. Let the therm run through it's cycle, and if the bower runs continuous again, let me know we can walk through that situation.
