I just installed a new programable hunter model 44110 thermostat and the fan will start but the compressor will not
the old thermostat was a carrier model hh01ad042 the only issue i had some question on was on the old carrier unit the red wire (R) was jumped to a terminal marked with the number (4)
all other conections were normal
green = G = fan
yellow = Y = compressor
white = W = heating
Do I leave the jumper in place on the new hunter unit, remove it, or something else?

Sounds like more is wrong than the thermostat. If gas heat,make sure the pilot light is lit and there is gas pressure.If fuel oil,you may have to press the restart button on the burner unit. or blead the the pump.
This sounds like a split system, the condensing unit outside and the evaporator coil and fan inside. You must be referring to the indoor fan, since the compressor and outdoor fan are controlled by the same contacter. The indoor fan relay contacts sounds to be welded shut, and needs to be replaced.
You may and an anolog stat and the old one was digital if so it won't work. Digital sends info to system anolog is just a set of points open or closed. Digital can carry tons of info to system like a computer. Like comparing a computer to a rock. Sorry but you need to go back to proper type stat.
you cant use this thermostat . you have a trane 2 stage heatpump the hunter thermostat is made for a one stage heatpump ...if this answer helped please rate this 3 or 4 stars , this will keep me in the paid answer department
I'm not familiar with that model # but most furnaces are similar. R goes to R (usually the red wire). If you don't have a seperate heat source, like a boiler, the wire needs to connect to both Rc & Rh. Stats usually come with a jumper in place. Then W to W (usually white), G to G (usually green) and Y to Y (usually yellow or blue). Before you make any connections, TURN OFF YOUR FURNACE. If you don't, you'll probably blow the fuse on the control board, or worse yet, blow your transformer.
The outdoor unit has failed in some way. This is probably not the thermostats fault. You can check the breaker for the outdoor unit by turning it off and then back on. If this does not work, the problem is most commonly one of the following issues. All of which should be done by a professional because the danger of electrocution.
1) Bad Start/Run capacitor 2) Bad Compressor 3) Bad Exhaust fan motor 4) Combination of some or all of the above.
