Having more problems with my Intertherm E2EB-017HB furnace. Last summer as some may remember, I had issues with my cooling coil. Condensation ran all over the components. Since that time I have had the coil replaced. This fall when I started my furnace everything seemed to work fine. However, if I turned thermo past 72, I would start to hear some chattering in the furnace. I opened the cover to see the contactors opening & closing. (You could see the flashing). Since I had water on the components I decided to replace both contactors & the breakers. (Duel breaker setup). Everything seemed to work fine... at least for a couple weeks. Friday I came home and smelled something hot. I checked the thermostat and house was at temp, so the furnace was off. However when I got close to it, I could feel the heat radiating off it. Further inspection found the heating element still on. Here is where is gets interesting. The only components I can see that I hadn't replced were the transformer & what are called the blower relays. I replaced the relays today, and still the same problem with both the heating element not turning off and the chattering relays after a bit of running. I will be replacing the transformer tomorrow. Each time I discuss this furnace with people, they talk about the sequencer. I know what they are, and what different ones look like. I have however, never found anything that remotely looks like that in my furnace. Is it possible that this one does not have one ?? My parts breakdown doesn't list any sequencer. (The parts listing is from Nordyne). I have checked all my connections against the wiring schematics I have, as well as the original photos I took before I ever took a single wire off this thing. All appears to be fine. Sorry this was so long, any feedback would be appreciated.
