SOURCE: carrier heat pump
fuse is usually a small resetable breaker on the side of the transformer, or a traditional screwin fuse with a plastic cap on one end that is a specialty fuse and is available at most motor shops or elec supply houses. or its a auto type plug in fuse on the circuit board usually 5 amps or three amps. first turn the fan switch on the stat from auto to on. does fan run? if it does you have high and low voltage and your wired wrong. if it is in the stat you are usually looking at red connects to red . yellow to yellow, green to green , orange to orange, white usually to white, that leaves a common power wire to operate the stat, usually connected to the common term on the new stat . this can be any color and is necessary for the new stat to think and work, if it has batteries it will have a display but it needs a red and a common to think and work. this wire can be any color and if your old stat had no common which a lot didnt then youll have to add one. carrier also has a emergency heat strip wire sometimes labeled x2 etc. you can usually jump white over to x2 to perform function if needed. good luck.

On the thermostat if its a manual on then pop the cover off and look for a small dial with numbers on it. Take and move it tpoi a higher number than whats it is set at. Its called a heat anticipater and is supppose to make it so that the unit does not oveshoot or under shoot like what your experiencing. If its a digital oine then you are going to have to configure the setting in the insdtallers menu.

Is this an electric or gass furnace - Eather of these can can have this problem its most recomendable that you call a seviceman .
in the case of electric furnace you may requier a new heat sequencer. And in the case of gass you may requier a new relay.
