Hello everyone I have a question about my furnace. It's a Evcon. Can someone tell me what the cool setting on my thermostat is for. It has 2 settings heat and cool.Does that mean it's a heater plus air conditioner?

thanks for the help

Hi, You're very welcome. It isn't real hard, but then I've been doing it over 27 years. I've seen many people miswire or cross-wire and end up with a repair more costly than a service call from start would have been. Knowing exactly what is there now is the key to getting correct t-stat and the dete...

thanks robert!

Are you talking about a jumper wire inside the new t-stat or at the furnace ? The t-stat you need will depend on current wiring and which a/c control box you have. You should really get a Tech to do this for you. IF you miswire or cross up the wires, you'll blow your low voltage circuit and have a c...

hi! robert & greg. its me again. got my refund check finally. the old thermostat we were talking about in my old post that went bad. its the style that only has a one sw. on it. a heat, cool, & off option selection. the other sw. that is inside the intertherm unit is the on, off, & auto ...

I am extremely impressed with this web site and your assistance. Thanks so much! I went a head and ordered new sequencers for both furnance. However, we will test the contactor also. Thanks again,
Kim

Contactor # 6922-3131 near bottom part of page @ $32 . You would test sequencer same as other one. On contactor, test those bottom 2 silver terminals on the side for 24 volts. Remove the top cover over center contacts. See if the contacts are pulling in and releasing over and over. See if the side c...

Hi Kim, You should read 240 vac across M1/M2 . That reading makes it possible it is partially closed. Let it run and when it keeps running, turn off power. Remove wire (? blue ?) that goes from M2 to terminal 5 of fan relay. Remove from M2 or fan relay #5. Turn power back on, does blower start and r...

There is warm air at first. This last awhile then cold air starts blowing from vents. We tested the Sequencer and these are the results: H1/H2 = 0 M1/M2 = 17 Do we need to purchase a new Sequencer? In addtion, our second vacation home furnace has a probelm. It is a Coleman Presidential Model 6806-73...

Hi, Do both or one of the Heating Elements also stay on ? If not sure, is the air from registers warmed ? Scroll the page to locate Sequencer # 3110-3571 @ $24.41. Click on pic for enlarged view. That's your Sequencer and it is located in middle of back wall of control box. Set meter for 24 volts/ac...

Yes we do have a multi-meter to test for voltage.

Hi,

It is either a stuck blower relay or a stuck sequencer.

Do you have a multi-meter to test for voltage and feel comfortable doing so ?

Thanks,
Robert

We have a Coleman Evcon Model EB12b electric and the fan does not shut off until you turn it off at the thermostat. We would appreciate any help.
Thank you!

I believe it is still available in a Large diameter SJ type cord.

Thanks guys. Just saw the same thing again on an HVAC install. In this case they took black shrink tube and shrinked around the neutral conductors on 10-2 running to a air handler...
can you still get 8-8-8 wire??
my local supply says no
