Q:

EB17b Electric Furnace EB17B Coleman / Evcon Ind. Furnace

A:

Thank you for your question. I'm sorry you are having this problem with the furnace and I can understand your concern. This type of problem will usually lead to a defective sequencer. This furnace looks to have 3 sequencers and one of them will control both the fan and one of the heating elements. I recommend having a technician check and make this repair. The technician can then also check the furnace to make sure the safety devices are working properly. I'm listing a site you can access, to schedule a tech to come out. Here is a link for the website: Sears Home Services or you can call 1-800-469-4663. I hope this will help you.

It's not really the ac it's the air handler inside

When you say your AC works intermittently, do you mean the indoor air handler runs intermittently or do you mean the outdoor unit?  Are we troubleshooting the heating or cooling cycle?

 

If you're getting 30VAC across the secondary of the transformer, what is your incoming line voltage reading?

 

The sequencer is on the heat strip kit that sends power to the individual electric heaters which is backup heat to the heat pump (if your outdoor unit is a heat pump).

Thank you for your question. I'm sorry you are having this problem with the air handler. If the fan quit running on a call for heat, the problem could be with the sequencer. To determine for sure, some voltage checks will need to be made. Only make these checks if you feel very confident that you can make them safely. Check for 24 volts between H2 and H1 on the sequencer on a call for heat. If the voltage is there, now check across M3 and M4. There should not be any voltage on this check. If you do get 120 volts, the sequencer will need to be replaced. If there is no voltage reading, now check at the blower relay from # 6 to the orange wire at the transformer for 230 volts. If the voltage is there, the motor will need to be replaced. If it's not there, the blower relay will need to be replaced. I hope this will help you. If you would like more assistance, reply to this thread and I will be glad to assist you further.

If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website: Sears Home Services .

Safety Notice: Be sure to disconnect the appliance before performing any troubleshooting procedures. If you are not comfortable with doing any voltage checks or repairs that might be recommended, please contact a local service provider for repairs. Be aware that there could be sharp edges inside the appliance that could cause cuts or other injuries to yourself or others.

Wow Scott! Thank you for your prompt informative answer! I was leaning towards the sequencer since the A/C ran fine all summer long and the unit shut down the first time heat was called for. Infact, I already ordered a new one and pulled the old one out before doing any voltage testing. Call it a strong hunch...I just hope I'm right. I probably will 'pop' it back in and do the voltage testing tho....Thanks again!

My apologies for not posting the end result sooner. Hopefully my reply will help others with the same model unit and problem. It turned out to be the blower relay. Plain, simple and fairly cheap. I also left in the new sequencer I purchased and kept the old one for a backup. Plus I replaced the old crappy working thermostat for a new Honeywell digital unit. All in all it cost me about $100.00 in parts. I think thats a small price to pay to have the unit prepped for the winter.
