Replaced a circuit breaker on our heat pump our air goes off right but the blower stays on what could be wrong


The blower relay (called a fan relay) is stuck and must be replaced.
Want to do it your self? Trace the two power leads from the blower motor. usually white and black for high speed, White and red medium.
(Blue,purple and brown are capacitor colors)the white wire goes to the line side of the contactor. the black or red wire goes to the fan relay. This arrangement allows the blower to continue running for a minute after shut down to dry the cooling coils or complete the heating cycle. (Line side is where the incoming power wires connect)

Amana heat pump emergency heat comes on but blower will not start. The call for heat comes in and the heating element(s) glow red for a few seconds and then there is a "click" and the heating...


Check the blower motor capicator. It should be mounted close to the motor with 2 wires to it (brown,brown/white).
Turn the blower on the thermostat and spin the squirrel cage by hand and see if it runs after by itself. If it does then definitely the capicator is bad .If it still doesn't run then check to see if there is voltage going to motor.
If thermostat is calling for fan and there is voltage present at the motor terminal then the motor is bad

Replaced Thermostat and now Blower Motor will not run


Sounds like a set up issue on the tstat. You say this is a packaged unit, inside the machine you should find where the tstat wires hook up. Typically red is power yellow is compressor orange is reversing valve white is emergency heat green is blower. Put red and green together, test blower. Then red green and yellow, make sure blower works again. If blower runs both ways it's either the tstat wire or tstat itself. Make sure you are landing wires on dedicated heat pump terminals, make sure in settings you are set up for heat pump with back up electric heat and TSTAT CONTROLS THE FAN. Good Luck. Also if there is a switch on the tstat for gas or electric on the back you want electric.

I am trying to install the new tx900ts in my house and i do not understand the wiring on it i have a old trane thermastat that has different wiring codes


PLEASE GIVE ME A RATING AND VOTE YOU NEED TO FIGURE YOUR WIRES WRITE IT ALL DOWN AT UNITS AND THE OLD STAT
common is different by installer so you gotta look at the units or you will blow out your transformer this wire will be blue or brown
24v always red
compressor always yellow
fan always green
reversing valve always orange
heat w1 always white
emergency heat will be either brown or black dependinting on installer if its a heat pump this it what you have but if its a gas system its much easier
red- 24 volt with a jumper already on the new stat
white- heat w terminal
yellow- cool y termina
fan green- g terminal
and common is optional with batteries so its not needed

02PTCRUISER HEATING UP SLOWLY BUT WHEN STOPED HEATS FAST,FANS WORK ,THERMASTAT SEEMS TO WORK WATER TURNS, DOESNT HAVE ANY ANTIFREEZE IS THAT THE PROBLEM?


of course thats the problem. if you had a manual on the pt you will find that this is a pressurized system and just water without antifreeze changes the boiling point. Flush the systen and put the correct amount of antifreeze in, and replace the radiator cap with a 12-18lb cap.

Heat pump cycling on and off.


It sounds as if you you have a low charge of refrigerant, r22. When the unit comes on outside, the outdoor coils become the lowside, there is a low pressure switch that is tripping out contactor protecting the compressor.

Rheem heat pump. blower will not turn off


The fans are set to delay for 60-90 seconds to remove all heat from the heat exchanger/heater elements.

If the fan runs any longer than 3-4 minutes after the Emergency Heat shuts off, you may have a bad sequencing relay in the air handler.

Heat strips not heating


Check your sequencers on your elements. If you don't have the equipment, then all you can do is check your filters and ensure they are clean. Also see if you can set the heat pump at a lower temp, you can do this at the defrost board, the therm or sensor. Get (the heat pump) to heat the house more than the electric before you have a tech come and diagnose your problem.
