Question about Heat Controller Thru-Wall/Window Air Conditioner

1 Answer

Heating not working like it should

I have a trane thur wall unit in one of my rentals. It is a year old and was removed from a hilton hotel. I had it put in its nice and level so I think. I had an electrition put a new plug on the end of it and new wall plug to match it up. Heater call for 20 amp and we have a 20 amp breaker. The 220 was already there for air conditioner. Electrition check it is drawing what it should. The unit when turned on will come on you can feel heat coming out just a bit, and thats on high. The fan does not come on when on heat mode. When turned to cold air unit kicks on harder then it does on heat, and the fan starts to turn. The air does blow and works. I'm not sure if it is working as it should though it does blow harder then when it is on heat. Please if you have any suggestions please let me know. Thanks Tim

The fan for the A/C should blow harder than in heat. The fan should be on high for cool and low for heat. You can change the heat setting for medium but I would not recommend it because it may make heat coming out feel less.

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!

How to remove front cover.???

Ive worked at barley heating and air for a good two years as an installer. But mainly on condensing units and air handlers. Post another video of the entire unit. It could be a "pop off" cover but I wouldn't risk it. Instead the screws could be on the backside of another pannel like the larger one that it seems to be attached to. But also let me add. I've never seen this unit and I've only done work on trane units.

Getting no readings on our Trane heatpump/furnance thermostat. Checked all circuit breakers and they are on and ok. Is there an internal thermostat battery that might need to be replaced? The units are...

Most wall mounted thermostats use a single AA Alkaline battery to power the thermostat. There should be a panel or door on the thermostat housing that slides open to change the battery.

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?

If this old unit has a outside transformer then you will need to shut off the breaker and take the wires off the compressor and tape them up. Then turn the breaker back on and it should run.

Wiring Trane/Honeywell TH8320U

use the outside designations for heat pump, and inside for standard, I would assume a heat pump since you have more than five wires attached to it now. Use the colors of the wire to match to the designations, use tan for y2, black for w2 rc and rh should already have a factory jumper. I would have to trace out the "U" and see where it terminates, I have not seen a bare wire on a stat in 27 years of doing this. before powering, verify the tan and black at the indoor unit circuit board and see if they are landed on the terminals designated at the stat. hope this helps

Trane weathertron thermosatat

OK. Here is a Trane Weathertron BAYSTAT240 thermostat wiring picture. This heat pump w/ electric (emergency) heaters is running right now. Notice the G terminal has green wire, the R terminal has red wire, the white wire is jumpered from W to X2, etc. The black wire loop you see in the center hole is unconnected.

This unit is adjusted by leveling the base - loosen the screw to the left of "R" and the one to the right of "F". Twist the base clockwise to RAISE the indicator. This makes the mercury in the switch turn ON at a different temperature. Remember to tighten those 2 screws again.

You will have to experiment several times to make the unit read exactly right. If the tech installed the base exactly level, the unit would read right (it says here).

No heating, cooling or fan.

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.

This link takes you to the TRANE contact page. They can answer any warranty/recall questions you have.

You need to replace your control board, but if you are can repair it by your self you can change the relay that supply the fan and condenser.
