Question about Heating & Cooling

1 Answer

No heating, cooling or fan.

I have a Trane PTHC1501GAA A/C Heat Pump. The unit stopped working after several years of trouble-free service. Now and then, in the winter (now) the unit will start up, run for a few seconds and stop. I believe this is the freeze prevention circuit. The unit is operated by the local controls only. I am unable to run in heating or cooling codes and surprisingly, not even the fan will run when selected. 240 VAC power is present, board fuse is good (28V present). I'm an electrican and don't mind messing with it electrically but the controls are unfamiliar to me. I have seen the the Goodman has a recall on this unit for a limit switch failure. I have checked my serial number (A96**) and found that it is affected by the recall. How do I get this service? Thanks!!

I'm confused. You have a Trane, but are asking about the Goodman warranty. I missed something there I'm sure, sorry.

"IF" Trane has a recall or warranty issue, then any qualified technician should be able to help you with that. The parts would be provided by trane in such an event, but unless the unit is less than 1 year old, chances are you will have to pay for the labor.

Being an electricain help if you want us to assist you in troubleshooting.

Brand New 2 weeks old 4 ton Trane compressor leaks a lot of water onto pad

If the unit is running in cold weather than there is ice building up on the coils located outside. This is normal in that the unit is running in heat pump mode heating inside and cooling outside, After the unit detects the ice build up it briefly reverses the cycle heating the outside coils melting(defrosting) the ice which you observe as water on the pad.

The video gives you an example of the defrost cycle!

Thermostat Wiring and Terminal Designations

Here is a list of each common terminal and what their commonly used for. Also listed is what colors are commonly used. NEVER ASSUME these are what you have. Verify all your wires by following each to each piece of equipment. This will help you to be able to match your equipment with the terminal.

- R, Rc, Rh Red wire, hot side of transformer
- C various color wires Usually the common side of transformer
- Y Yellow wire, Energizes the compressor, cooling or heating and cooling for heat pumps
- W White wire, heating for most units
- G Green wire, energizes the fan or blower relay.
- O Orange wire, energizes cooling on most heat pump units
- B Blue and sometimes Orange wire, energizes heat on most heat pump units
- B or X Blue, Black, or Brown wire, the common side of the transformer when the t-stat needs a common. Some brands use B as the common (York, GE, and Trane)
- E Pink, Gray or Tan wires, Emergency heat relay on heat pumps with auxiliary heat
- T Tan or Gray wires, For units with outdoor anticipator reset control (Trane, American Standard, GE, and Carrier)
- W2 Pink, or Brown wires energizes second stage heating on 2 stage units
- Y2 Blue or Pink wires, energizes second stage cooling on 2 stage units
- L Can be most any color, energizes service indicator lamp on units that are equipped with that.

The wires that always cause the most confusion are the B and X wires.
Check out the B terminal first. The NEMA standard for the B terminal to be the heating changeover valve but with some units it is different.

Trane, GE, York and some other manufactures which includes older Honeywell thermostats often use it for the common side of the transformer.
“X” Usually is the standard for common, but just like “B” some manufactures do use “X” or “X2” as the terminal for the emergency heat relay.

normally most systems can reverse the flow of refrigerant to act for heating but in e-heat mode the system is pushing heat in by its own internal fan only in normal heat mode however the system may take a while to adjust and turn on but as stated in e-heat mode it may only push heat in by its own internal fan some systems may do this

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!!!

Trane xr12 heat pump switching to aux

Sounds like the compressor is not running. Possibly a bad capacitor. Check system in cooling, see if it cools. If it does cool then you likely have a reversing valve issue. Good Luck!!

Outdoor fan does not come on

most likely it the the cap that is bad. Is this in heating or cooling mode?

I have a 20 year old Trane heat pump. Outside

Yes, you will want to put the unit into cooling mode to help assistance with the ice melt.

If you can, block off the outdoor coil or disconnect the outdoor fan motor. This will assist in raising the discharge pressure and temperature and thus, it will melt the ice quicker.

Or, if you have the capability, you can take a garden hose around to the unit hooked into hot water and melt the ice that way.

If your control board is messed up, why aren't you replacing it?
