Sounds like you have a bad fan relay, the fan should shut of within 30 to 120 seconds after t-stat is satsified.

SOURCE: Heatpump A/C not working

First,Turn on the heat cycle (Not Emergency)and see if the outside unit come on,If not,and you don't have low voltage outside,Go to the inside unit and test the transformer,If you have low voltage from the transformer but not outside,It is the low voltage wires,If you don't have low voltage from the transformer,It's the transformer.If you have low voltage outside when in heat mode,but the unit won't come on,It's the contactor.Let me know if you need more help.

How do I reset the temp my heat pump switches from electric to gas. It runs much more economically on electri than on propane. The thermostat is a Honeywell th8000. Code 350 setting I believe. Thanks


Heatpumps are more complex than an AC unit. Yes, there is a difference between a heatpump and an air conditioner. Where the real difference lies is out side in the condenser unit. There's a defrost board out in the unit, and depending on the brand and model, one of the wires will need to be changed so that the gas furnace will not come on. The problem with this, heatpumps use the heat that is available from the outdoors and transfers it to indoor. When the temps outside drop below 50 degrees, there's not enough latent heat to transfer, thus calling the propane furnace to operate. Without the addition of the furnace, you will not be able to heat the area properly. The only way to remedy this, is to remove the propane furnace and replace it with an electric airhandler with a heat strip for "emergency heat". The emergency heat term is used when the temps drop below the temps I mentioned above and calls for the heat strips to come on.

WIREIN HEAT PUMP FOR COOLING ONLY


You must wire Orange from heatpump low voltage wire to gether with your yellow s and you must have a common wire usealy common comeing out of heatpump should be black color than what ever color wire you have connected to common at t-stat and airhandler connect that to black wire at heatpump. To make sure blablack I s common follow wire up to board and it will be connected to C terminal now you will have ac all time. If you want heat remve Orange wire from reds at heatpump and you will get heat only.note when doing your wireing make sure high voltage is off to heatpump and airhandler hope this helps

My unit is not putting out power to the thermostat. It's a heat pump with aux heater. Voltage tested between R and AUX/W2 posts show no Amps. What could cause this?


You have to go to your indoor unit its called a airhandler check high voltage going to unit should be 240volts .if you have 240volts look to see if there is a fuse either on the board or in line it will look like a car fuse 3amp or 5 amp check if fuse is blown but before checking make sure you pull disconnect so you dont have any high voltage going to unit. If fuse is blown get same exact fuse auto parts store will have them replsce put stab back in diconnect unit should run .if there is no fuse in airhandler keep high voltage on go to transformer and check for low voltage comeing out of transformer .NO 24 volts comeing out .replace transformer.if you have 24 volts comeing out of transformer check low voltage wireing thermostat wireing one goes to thermostat and other goes to out door heatpump usealy Brown in color and will have 8 small different colors wires inside brown jacket. Check for 24volts between red wire and common should be blue color if it is color coded. If no voltage there is a break in red or common wire.or sometimes just wirenuts need to be retightin.also when checking for low voltage one leed must be on common and other lead goes to red.also with high voltage off take face off thermostat carefully make sure all connections are TIGHTEN. This will also so you witchcolor wire is common it will be connected to C terminal hope this helps.note must have 24volts red and common or t-stat will not light up.hope this helps

Had 16 xi Trane heat pump installed 3 years ago. It ran well for the first couple of years. It began to stop heating and would blow cold air only. Have tried both aux heat and reg. heat to run and neither...


That's a complicated system that needs a qualified technician to service it. Lots of people can install them and they run fine, for a few years. Your indoor unit, operating on 2 heat elements, will feel like its blowing cold air even though its heating, just not so well. And not like you are accustomed to. Each element (5kw)=22.7amps, on average. So 3 elements operating should trip a breaker. Its probably been operating on 2 heat element plus the heat pump. And now you have trouble with the heat pump. If you can't TRUST the guys working on your equipment, try someone else. A second opinion. Normally a 3 or 4 ton unit will have 15kw heat installed, heatpump or not. 5 ton, 20kw. If yours is a 3-4ton, cooling, the 100amp(or normally two 60 amp) breaker should have been installed upon equipment change out. If yours is blowing cold all the time, something is wrong with your heatpump. The electric heat inside operates only when the heatpump can't keep up(real cold outside), the heatpump is in defrost(then it's actually in cooling mode), or if you have the tstat in aux/em. heat. Try a local trane dealer? Of a technician with 15-20 yrs under their belt. A trane dealer should have trane tech support also. BIG HELP!!!

We just installed a dometic heat/air pump .#630515.321/65151.301co .the thermostat is not reading the heat pump and it also will not stay lite. Can you help?


It sounds like you have a problem with your wiring. You have to make sure that all signals are complete through out wiring. Ex. Y goes to the outdoor unit on usally yellow, G goes to the g signal on the airhandler, W goes to he w signal in the airhadler and outdoor unit. O/B goes to the oudoor unit, R goes to outdoor and airhandler, C goes to outdoor and Airhandler. Check your wiring and also make sure you have the correct thermostat, meaning you have a heatpump thermsotat.

Thermostat Wiring Problems!!!


. your blue is probably common and if you hooked it to Y you shorted the transformer or blew the low voltage fuse. Green is fan, yellow is AC, Red is 24volt. Is it a heatpump or just ac? I think its probably a heat pump and your brown is your Reversing valve it needs to be hooked to O on the new stat. If its a heatpump your tstat must be a 2heat 1 cool stat w/ aux heat. Without knowing what terminals the wire were hooked to on the old stat you may have to look at whats hooked up at airhandler( furnace) and on A/C (heatpump) tobe able to determine what goes where on the new one.

Programmable T stat


your trane heat pump energizes the reversing valve with O - orange y - is to turn on the unit make sure you have your orange wire hooked up and the tstat programming set to heatpump otherwise your reversing valve might be bad

My carrier air con unit is a problem


There is a low voltage wiring problem. Make sure your t-stat wire is in the correct positions and that you have not removed the jumper wire at the t-stat. There should only be 2 control wires leaving the airhandler and going to the condenser unit outside. Unless it is a heatpump. One wire goes to common and the other goes to the Y terminal. W terminal is for heat. The unit will cut off if you have the unit calling for heat and cool at the same time.
