Why did the air handler on my 1999 Trane heat pump stop working? Could it be a fuse in outside unit


The fan is controlled by a relay that is operated by the thermostat. There is usually a wiring diagram inside the unit that will show the location of the relay.

WIRING THE THERMOSTAT TO AC UNIT THEN FROM THE UNIT TO HANDLER


Generally, you would go from the thermostat to the air handler, and then, from the air handler to the outdoor unit. I don't know if you have a heat pump or not, so I will give you a simple diagram and you can contact me if you need more.

Thermostat : Y G R W and sometimes C
Air handler: Y G R W and C
Outdoor unit: two wires connecting to the contactor ( not heat pump)

Thermostat; Y--------------Y(air handler cooling)------------------one side of contactor, outdoor unit
G-------------G (air handler, fan)
R--------------R (air handler ,hot)
W-------------W (air handler, heat)
C--------------C (air handler, common)------------other side of contactor, outdoor unit

This is a typical wiring diagram. Just contact me if you have something different. Hope this helps. Stay cool. mark

Upgrade Baystat 239 to a Honeywell RTH7600D controller


For Trane sytems, B is your "Common" wire. O is your reversing valve relay, G is your fan, Y is your compressor contactor, R is Hot, Brown will not be used on your electronic tstat. X2 is your backup electric heaters. Without knowing what terminals are on your new tstat, I cannot offer more information than this. The installation manual may indicate what each terminal is controlling. I strongly suggest to write down ALL of the terminals and colors from your old t-stat and be sure to turn off the power to your air handler. Put the fan switch on your tstat to ON before turning off the power. Make sure the fan is running. Then turn the power off to your Air Handler. If your fan stops running, you have turned the power off to your tstat and are ready to start replacing it with your new tstat. I hope you find this helpful. Good Luck!!!

Hello i want to conect a trane condensator 2twb0036a1000ba to a trane evaporator mww536k10raa i need a wiring diagram


Your wiring concerns may be more with the thermostat wiring connections than the condensor connections. if you look inside the cover of the evaporator unit (usually called air handler) there should be a wiring diagram glued to the panel cover. This diagram will show all 3 units (stat,cndsr, airhndlr) and the wiring needed between them. Trane and Lennox are notorious for having the most wiring between components. You also need to be sure the stat is the correct type for the system (i assume this is a heat pump system) and there can be as many as 9 wires from stat to system and 6 wires from inside to outside units. Also, the stat will have a wiring diagram with it that shows most typical system wiring including the wiring between in and out units. Your best bet (if you have no diagram on the unit or with the stat) is to call trane and have their tech division fax a diagram to you. Goodluck,Macgivor

Need a wiring diagram for a 1977 GE heat pump air handler


your not going to be able to find one. Its just your basic wiring like pretty much every Trane on the market.

Only difference would be the lack of any type of control board. Back then, it was all wires relays.


What are you looking for specifically?

Trane Air Handler and Trane Thermostat with no power. Please help


First of all put back the jumper wire you remved Rc to Rh and also put the red wire to either one then the white to W, the green to G and the yellow to Y .That is for the thermostat wiring for a not heat pump outdoor unit.Remember this electronic thermostat has a time delay so the unit will take a few minutes to start.All this if the problem is the thermostat.But also when nothing works it could be that the drain line is clogh and some air handlers have a flood switch who shut the unit off if drain is clogh(it could be located in the drain line out of the air handler or inside it on the drain pan.) newer TRANE units have it inside.

Temp in my home will not drop below 81 degrees


Air Handlers differ in the way they adjust there variable speeds. Carrier you just plug into a pin. Trane has dip switches with directions on the fan housing. Before you try to adjust please kill power to air handler. Varriable speed are very sensative to voltage. If I new your air handler brand I could help. But just check the wiring diagram and they may ahve dirrections on there for setting speed. Need more help call back Rus

Trane air handler cycling rapidly


Depending on the age of your Trane unit. The fan relay has a time delay. This is a solid state board on the relay. Most of the time they stick on or off. Check for loose wires. But start with relay.

Trane air handler model #TWV036B140A Fan wont stop


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