Tempstar heat pump: want to bypass defrost thermostat

Our heat pump is wanting to go into defrost mode constantly when we have it turned to heat. It attempts to go into defrost, but it sounds as if it keeps tripping a switch on and off and it repeatedly gets louder. So we end up using the emergency setting when this occurs.

We live in Clearwater, FL and I don't think we really need the defrost cycle. Can I bypass it? It's a Tempstar heat pump that was installed when the house was built in ''91''. It has served us well with no problems.

Thank you for your kind response,

Mr. K. Greene

Don't attempt to bypass defrost mode. If it's cold enough to use as a heat pump, it's cold enough to need the defrost cycle.

It sounds like a sensor issue, although it may be the controller board.

Unless you know how to work on equipment like this, I urge you to get a professional to service the unit for you.

Sound to me that you might have more of a defrost sensor problem or micro board in the condenser (outside unit).. and no you should not bypass what its design for, it can hurt your unit... and at 18yrs old unit.. thats a good one...good luck..mike

I have a duotherm AC unit. Which two wires do I jump to bypass the thermostat

Hey David if you are wanting to bypass the thermostat to make the air conditioner come on you would take r which should be red and y which should be yellow,. Tie them together. This gives the outside unit a constant 24volts( call for cool). If it is a heat pump you would also want to take o which mostly is orange and tie them with the red and yellow to energize reversing valve. If not it will be jumped out but be in heat mode. R to w(white) would turn your heat strips on. If your thermostat is bad and you plan on leaving it like this temporarily also take g (green) and tie it to red and yellow. G is your inside fan. Basically r is your 24volts so you tie it to what u want to jump out y= outside unit o/b=reveesingvalve if heat pump g= inside blower w{ inside heat strips. C is common never jump c to r or you will blow a fuse or transformer only reason you would have c at thermostat is so it can run without batteries. Hope this helps

Heat pump runs on electric when outside temperature is higher than cutin

Check your thermostat and heat pump owner's manuals. Thermostat may be programmed to require electric heat at higher temps. Also could be bad outdoor temperature sensor tied to
Heat pump system controls (I had that problem) When was it installed? Warranty thermostat and or Heat pump? Call installer
Thermostat programming is a headache. No help from installer? call customer service heat pump and thermostat. Some possibility of bad installer wiring. There is also a heat pump "defrost" cycle. Usually the Electric coil will turn on to compensate for the Defrost cycle which is just the standard air conditioning mode therefore moves heat from inside to the outside coil to melt the frost. This cycle may be occurring too often. I had that problem. Fixed under warrantee.
Heat pumps are complex machines. The controls even more.
You need a tech, hopfully you are still under warranty.
Hope this helps.

Why contactor on heat pump will not energize heat mode?

Heat pump and AC are basically working the same principle. When you turn on the heat pump is just like to turn on the AC. The main contactor will energize to turn on the compressor. The only difference is the 3 way valve, either switching to AC mode or heat mode. It is the most commom problem for heat pump. Check the thermostat wires for heat mode and defrost control.

Heat pump will not turn on

I would call an expert, testing needs to be done, but based on what I have seen it may be the control board of the heat pump is defective.

You can start with a heat gun or good hair dryer and defrost. Upon doing this you need to locate the defrosting element and this is where your problem will more than likely be. You can use a volt ohm meter and check for resistance or open connection. Some times even a blown element will show continuity it will just be lower than normal. Just an educated guess and strong feeling this is the culprit. I certainly hope you did not toss out the defrost control board because now you have a spare. Take your time in pulling out the old element and secure the new one properly, vibration is not kind to elements.

My heat pump is frozen up today and it is 60 degrees outside and I have my heat set to 66 degrees. Is this normal?

You post is not clear as to where the freeze-up is occurring. I'm going to assume the outdoor unit is frozen up.
Heat Pumps don't generally freeze up at 60 degrees. If the ice around the unit has an uneven pattern (for example a thick spot around the center or at the very bottom) could indicate a low refrigerant charge. If the ice is even throughout, it may be one of the following:
*Sticking Contactor*.....turn the system off at your thermostat and check to make sure the unit outside shut off. If it doesn't turn off, it is likely to be the contactor.
*Failed Defrost Thermostat*.....if the defrost thermostat fails "open", the system will never go into defrost.
*Failed Defrost Control Board*......this could also prevent the system from going into defrost
*Failed Reversing Valve*........put your system in COOL mode and check to see if it will blow cold air inside approx 16 - 22 degF lower than room temperature.
*Failed/Failing Condensor Fan Motor*.......ensure the condenser fan motor is running during heat and cool modes. The condensor fan motor will not run in OFF/Satisfied Mode or in Defrost Mode.
I hope this helps. Good Luck! :-)

HELP!! I got a problem with my A/C

I looked at the pdf file page 20 of page 124 for t-stat says for a Y594g1476 to remove the jumper IF W1 is used. I don't know if you have 2nd stage of heat such as electric heat. I would check wiring according to your outdoor unit and indoor unit and the t-stat. At the very least you will need R and it looks like X terminal giving you the 24 volts. for the control circuit. O is for the reversing valve. G for the blower. Y for the compressor contactor. W1 goes to the fan section to operate 2nd stage heat if you have it.You can also remove the t-stat and make sure you have the correct subbase which the PDF file shows for a y594g1476 stat it should be a Q674 series. Also what you can do with the stat off is jump out R to G to O to Y that should bypass the t-stat and bring on the fan and compressor contactor and the reversing valve. ( reversing valve is energized in the cooling mode ) see what happens ,you may have a built in 5 minute timer before it starts.I was unable to find the PDF on your Tempstar. So I am not sure what the outdoor coil temp. sensor is. I know that to initiate a defrost heat pumps use an outdoor sensor strapped on the outdoor coil bend. it usually labeled DFT (defrost thermostat ) but that should only work in the heat mode. Also they may show an OPITIONAL outdoor sensor/stat to stage 2nd stage of heat if using electric heat. But as far as I know that is installed by the contractor and is optional. In closing I would double check the control wiring from the t-stat to the outdoor unit to the fan section. Then I would bypass the t-stat with the method I told you. You can also take it one step at a time R to G blower fan starts .R to O reversing valve energizes. R to Y compressor contactor closes (after 5 minutes).Also the PDF shows an optional outdoor sensor that hooks up to the thermostat. If your handy with a volt meter check that you have 24 volts between R and X terminal at the stat
