I want to install an echobee smart thermostat to my Carrier

I want to install an echobee smart thermostat to my Carrier 58MCA furnace. The echobee would like 5 wires but my current thermostat only uses 2. Can I wire a new cable with 5 conductors from the control board to the Echobee? I did notice in the manual that the control board has 5 connections....JA: Just to clarify, do you think this is a larger HVAC problem, or something specific to the thermostat?Customer: No.....just wondering if the control board connections are industry standard.JA: Do you plan on doing the work yourself?Customer: yupJA: Anything else we should know to help you best?Customer: I have electronics and electrical experience

I have a Nordyne Furnace Model E2EB-012HA Serial #

i have a Nordyne Furnace Model E2EB-012HA Serial # E2E9903-00019 . We have had it in our manufactured home for 15 years. The problem we keep having is is works fine then it stops putting out heat. The fan blows but no heat is produced. We changed out the Thermostat last year. Have a new filter. Last night I tried the usual tricks to get it to reset by restting on the furnace, on main electrical panel for house and on thermostat and got no heat. Left for work today to return at noon to get help and the heat was on. This is an ongoing problem and need a starting point to go. My husband is in hospital and do not want to be taken advantage of.

I had a new Carrier furnace installed about 6 months ago.

I had a new Carrier furnace installed about 6 months ago. The ducts were also changed. Furnace has 2 speeds. When the furnace first starts in the morning there is a deep thud that resonnoates through the entire house. Sounds like a helicopter hovering or a large semi-truck idiling outside my home. It does this for about 15-20 minutes, when (i think) the higher speed kicks in. Any ideas?JA: Did you check the furnace's filters?Customer: yes it's cleanJA: Do you plan on doing the work yourself?Customer: depends on the diagnosisJA: Anything else we should know to help you best?Customer: No, just that it's hard to sleep with the low thump that resonnates that way
