    Yes it's possible but an expensive and difficult repair. Does it cool? I would get a tech. out.

Verify power to the reversing valve relay.
Some reversing valves energize in HEAT some in COOL.
Tap the reversing valve with a hammer handle while it is on. If it is stuck, it may come unstuck.

Why does it shut off after it starts ? 2a6b3060a1000a american standard


It sounds like a stuck reversing valve stuck in heating mode based on a hot refrigerant line.
It could be stuck in the heat position because it isn't receiving 24 volts to operate, or it could be stuck internally.
Tapping on the copper tubes on the reversing valve sometimes frees one that is stuck internally. It is copper so don't get carried away or you will destroy the reversing valve.
Did you feel the temperature of both copper lines?
If the reversing valve is stuck in heat, during the winter, your heat pump will ice up, because it isn't reversing to cool as it should when it calls for the defrost cycle to occur.
Google "heat pump reversing valve" to see what one looks like
You'll need to use a voltmeter to verify that the reversing valve is receiving twenty four volts.
Pull the two wires at the reversing valve coil and check for 24 volts.
If you don't have 24 volts there when you put the unit in cooling cycle,you either have defective thermostat wiring, or a defective thermostat.
If you have 24 volts you will need to check the electrical coil that the two wires plug into.
Set the voltmeter to ohms, and make contact with the meter leads onto the terminals of the coil. One lead goes on one terminal and one lead on the other terminal at the same time, to check for continuity. You should get an ohm reading. That means the coil is good.

If the meter indicates "0" ohms the coil is shorted and needs replacement.
If the meter doesn't read any ohms at all that means that the coil is burnt out and needs replacement

When the reversing valve is activated there will be a "whoosh" sound you can clearly hear if you are near the outdoor unit.

You can order the A/C parts you need online unless you have friend that is a HVAC tech and he could get one from the Trane supply house.

It is a big job to replace the reversing valve involving freon removal and brazing. Hopefully you will find the problem in the wiring, Thermostat, or the reversing valve coil.

Why does the heat pump operate in heat when cooling is set at the thermostat


You could have a problem with your controller

You could have a Wiring Issue that is not allowing the switch

You could have a Valve Issue....

Bryant furnace model FX4C, FY4A with heat pump and a/c will not switch from a/c to heat pump. Only have heat with emergency heat on.


WELL this could be a couple of problems the reversing valve could be stuck either from not enough pressure which would be a leal and low on freon or the unit is off on low pressure switch/high pressure switch from either being low on freon or something restricting it and caused unit to shut down, ive been a servicer for many years and if it gets below 30 degrees outside i would recommend running the e-heat anyway it does cost more money minute for minute. but you will find it will heat alot faster in those colder nights than the heat pump therefore cost is about the same.
as far as not switching over could be low on freon or a stuck reversing valve... is the outside even running in cool mode if not the you may have a tripped pressure switch...good luck

I have a older Intertherm heat pump that has quit heating but still cools alright does anyone have any suggestions what could be wrong??


Check your reversing valve, When you set your thermostat for heat the reversing valve circulates the heated freon through the air handler instead of the cooled freon. The valve is called many things but it reverses the flow of freon See http://www.google.com/images?hl=&q=heat+pump+schematic&rlz=1B3GGGL_enUS329US330&um=1&ie=UTF-8&source=univ&ei=npcOTfLEPMO88ga4poDGBQ&sa=X&oi=image_result_group&ct=title&resnum=2&ved=0CC4QsAQwAQ&biw=1024&bih=576 and look at the different schematics

Heat want shut off


I am assuming you mean it will not shift from heat to A/C. This could be because of a stuck reversing valve. You can tap it lightly!!! on either end but not on the side because if you dent it, it will for sure be stuck then. This could also be due to a low refrigerant charge and it just isn't cooling.

Intertherm Heat Pump


Some of the old heat pumps made the reversing valve in the heating mode. On your new thermostat the orange wire will need to be on the B terminal. If it was color coded? I hope you made notes of how it was.

Hi, if this is a split system with a remote condenser It sounds as though you are having a problem with the thermostatic expansion valve on the heating cycle. If indeed this is a heat-pump, it has 2 metering devices that meter freon into the evaporator to heat or cool. The reversing valve changes the direction of the flow. If the condenser starts to ice up and shut down and repeat itself. I would say that is you're problem. This is something that would have to be changed by a service tech do to the equipment required to do this. I wish I could offer you a quick fix but I can not. You can let me know if this is a split system, and I may have other solutions for you, so get back to me on this please.
Sincerely,

Reversing valve issues.


You will need to replace the reversing valve. You cannot replace the coil with a remote sensing bulb on this unit. Usually you know when reversing valves get stuck when you are having low side problems with heat working properly

You can't replace a reversing valve (must remove ALL refrigerant first), unless you are EPA certified and have the equipment to recover the refrigerant and to braze the old valve out and the new one in. That said, it's probably an electrical problem anyway. Could be the thermostat, the thermostat settings, the wiring between the thermostat and the furnace and the condenser, or the controls in the condenser - probably not in the furnace. If you don't see anything wrong you're probably gonna need a pro.
