In Need of help with Nordyne furnace

[wilson hembrey]

ok I am going to start from beginning I have a Nordyne E2EB-012HA furnace well i came home one day at the end of summer and the air was running but it was real humid turns out the heater,ac were both running and the blower motor wouldnt turn off I was told the sequencer was bad.I replaced the sequencer and the thermostat. Needless to say it still is messed up now the heat will only run on ac mode and we are turning the heat off with the breaker Does anyone have a clue on what the problem might be. I made sure I wiring was correct.

Who replaced the thermostat and sequencer? What thermostat is it?

My name is DeeDee his mother and I replaced it. I have experience with mobile homes repairs I used to have a few trailer parks but I have never had this problem?

fan control board ' time to call a pro

[wilson hembrey]

the old thermostat was a mercury slide style thermostat I put a identical one and finally put a digital one on it the digital one called for a 4 or 5 and i have 4 wires and it came with a jumper to connect the 2nd red wire

but the when I replaced the sequencer the blower motor does turn off it just is runnin backwards lol

[keeplearnin]

running backwards, wow how did you do that? anyways you gonna be sorry if you don't stop now, t-stst is one thing but now your talking blowers call the tech

[wilson hembrey]

could it be the capacitor?

I believe you have reached your limit as far as ability to rectify the problem Wilson. Sounds like more than one issue and throwing parts at it will become expensive. DIY is against the rules in the general forums here so further technical advice probably won't materialize you would be best served by having an HVAC company take a look at your unit.
