First you must be commended to be asking the question BEFORE you go and buy the wrong thermostat, and then try to figure out how to wire the unit, all while not having heat. Look at all the previous posts here about needing help to connect a thermostat, and it is getting cold in the house, and you will see what I mean.

The following links are some general help regarding thermostats, the third as a sample of how complicated the wiring can be, esp. for heat pumps:

Sure sounds as if you have a heat pump, with two auxilary stages of heat, this being refered to as 'Multi-stage".

And as you already know, there are many thermostats to choose from. Now I am a proponent of hiring professionals to consult and do work that a homeowner is not able to do on his own. Should you decide to tackle this job yourself, there is some prep work you must do.

First, you really need to understand exactly what type of system you have, for several reasons. One is obvious, know how your system is working, what is working when. Once you know what and how your system works, then you will know when it is not working properly to be able to take advantage of it's proper operation for your comfort, and perhaps realize some energy savings, along with the proper maintenance of the system.

Where is the temprature plug in on the motor?


I don't know if you have the six or the eight cylinder, but not really an issue. Look on top of the engine at the front and follow the top radiator hose to the engine. You will see the thermostat housing that the upper radiator hose connects. Right there close you will see a sensor that screws into the block or the thermostat housing. Should be just a single wire that slides onto the top of the sensor. Good luck.

How To Replace My Thermostat...HELP!


Termostat is as follow. See clarification. R U changing the sensor?
Follow the top radiator hose over to the engine and where it connects to the thermostat housing. There should be two bolts holding the housing to the motor. Remove the housing and replace the thermostat and gasket. The larger side of the thermo goes in the engine.

Thermostats being replaced often


I have repaired A/C commercial and in dustrial for 40+ years. ( ot of ten times replacing one item as a t-stat 5 times pretty much proves it is not the thermostat. The VA rating on your transformer has to ne able to carry the total load of your circritry.

Yes, I have als seen cases wher a intermitent short occurs in the thermostat cable that has up to 6 different wires in it.

Also "Heat anticipators" in all t-stats (Unless they are automatically controlled) need to be set properly.

You need a AMP reading meter with a Volatage and Resdistence Meter.

I suggest calling a professional. ONE WHO IS LICENSED TO WORK ON THE MODEL OF AIR HANDLER AND CONDENSER YOU HAVE. THE T-STAT MUST BE WIRED CORRECTLY TO THAT SYSTEM. TRANE, CARRIER, RUUD, GOODMAN, ALL ARE DIFFERENT IN COLOR CODES FOR WIRING.

I had one job wher a painter had nailed through the t-stat wire inside the wall and caused a short between the Red (Hot wire) and the ground wire ( in this case it was the blue wire) Depending on the t-stat ... There ar up to eight terminals that need to be i9dentified and then properly wired.

Heat pumps use at least 5-6.

5 t-stats failing is gettin close to $500 of repairs if not more.
