Hi Robert, This is what you had previously wanted me to do: Remove wires from M1 and M2 ONLY. Turn t-stat OFF. Set meter to test for ohms and test across M1 and M2. Then set t-stat to Heat-Auto-highest temp setting to get a call for heat. Wait 30 seconds and test ohms across M1 and M2 again. Tell me...

Hi Robert,

I'll get some readings for you. Why would you think that things are running normally now by moving the fan blower blue wire to what would be M6?

Thanks,
Jim

Hi Robert, Again, thanks for writing and for your incite. I just got back from taking some reading and made an interesting discovery. The old sequencer and new sequencer have basically the same part number but the new sequencer is not labeled M1/M2, etc....it is labled H1/H2, etc. They both look phy...

Hi Robert, Thanks for the reply back and wish it were better news. The funny thing with this unit is that the only thing wrong originally was that one of the heating elements was tested faulty. It was cost effective to simply replace all three elements and with a good cleaning out of the blower fan,...

Hi Robert, Here is what I have for numbers. Blower housing assembly:0106-881 Blower motor: 3500-590 S/N for furnace: 088878254 Hope this helps. Please let me know what is going on and what I need to do or replace to resolve the blower not coming on with the heating elements. Right now, I have the bl...

Hi Robert, My problem with this furnace continues but do have some additonal information for you to consider. The current situation is with a coleman furnace. The fan blower was not coming on when the heating elements came on. The elements would be on for several seconds, then cycle off. This would ...

Hi Robert, Thanks again for your reply back and your patience with me and this problem. There is another wire connected at M2 (a yellow wire) just as you described. I will test the element terminal for 120vac and let you know what we have. The furnace was having issues and the local repair company w...

Robert, First off, thanks for your patience and your advice. From your last posting, I checked both the blower motor capacitor and also the connector where the wires come together. The issure remains, but did do some testing with my electrical tester to try and determine why I'm not getting 240V to ...

Thanks for posting a reply. Any help is much appreciated. I have tried spinning the blower motor which turns freely. When troubleshooting, I did give the blower an independant power supply to 120v and both the low and high side did work and the motor seems to run quiet and smooth. If the blower runs...

I have a Coleman furnace model 3500-816, Serial Number 088878254 (54,000 btu’s). 1. We had a heating element not functioning, so we ordered and installed both heating element units (total of three elements). 2. We also had the blower motor cleaned as it was running out of balance, but after cleaning...
