I installed a goodman 5 ton heat cool unit and a 5 wire battery operated tstat, the unit is 2 stage will it work with this tstat cant get anything to work even jumping the tstat


See if there is 124 VAC across the common and the red wire. If not then the thermostat transformer inside the unit will have to be replaced or the fuse changed if it has one(not likely).All t/stats are not the same. If your T/stat doesn't have a provision for the 2nd stage or emergency heat then you have the wrong T/stat That will definitely blow the transformer that supplies 24 vac to the control relays

Carrier OEM to Honeywell Programmable Tstat - NEED HELP


you likely have a "two stage" system, but not a two stage heat pump. the first stage is probably the heat pump itself, and the second stage is the auxilliary resistance heat that suppliments the heat pump at lower temps. if i knew the terminals that are available on the new stat, i could advise you on the proper wiring.

From the Isolator panel, how do I connect the condenser, and the blower?


MOST UNITS NOT HEAT PUMPS  WIRE UP WITH 2 WIRES TO CONDENSER RED WIRE AND WHITE . WHITE GOES TO COMMON C ON FURNACE AND RED TO Y TERMINAL OF FURNACE Y ALSO GOES TO Y ON TSTAT. BOTH YELLOW WIRES MUST MEET AT Y OF FURNACE.  WHITE FROM STAT TO W   GREEN FROM TSTAT TO G AT FURNACE IF YOU HAVE C ON TSTAT HOOK UP BROWN WIRE OR BLUE FROM COMMON TERMINAL WHERE YOU HOOKED UP CONDENSER WHITE WIRE AT FURNACE TO TSTAT , MOST THERMOSTATS DONT NEED C RUN FROM FURNACE. THE TWO WIRES GOING TO CONDENSER IS -  AND + TO ACTAVATE CONTACTOR IN OUTSIDE UNIT

Reversing valve wire kills either heat or AC


Your solution is throw that Hunter tsat away and get a good one. You need one with 2 stage heat 1 stage cool heat pump tstat. Heat pump tsta has w,y,o,g,w,rnad w2. Don,t buy one without this one it. I have been in this business 45 years and people are always getting sold the wrong tstat at Lowe or Home Depot. Those guys dont know jack about Tstats. Keep in touch Rus GOOD LUCK. Get the right tstat follow the letter on wiring and you wont have any problem.

My Goodman Manufacturing AC unit won't turn off when it has reached the correct temp. It just keeps getting colder and colder. This is also with a new properly functioning thermostat.


You may have your Tstat wired wrong I run into this problem when somebody tries to install there own Tstat. Sometimes where they buy them does not give them enough info. Disconnect the Y and the g lead off stat and see if unit stops. If so the problem is the tstat. Most of the time the customer is given the wrong info by the saleman. Remember these guys at home Depot or Lowes dont know jack about Air Conditioning. A lot of the time they do give people the wrong tstat. Rus

Thermostat is not working properly. Readings are not accurate, and I've replaced the batteries several times for a few weeks now only to find they are leaking...watery, grayish substance all around the...


You need to replace your tstat. Very simple npt hard at all. Go to home depot or walmart by a new tsta. Make sure it matches your old stat. Turn off poer to Air Handler and replace wire to wire. Rusty

Wiring match-up


If this is a standard heat cool unit. You have a tstat with rygwcob. Just color code the wire to the unit. Some air handlers such as Rheem and carrier use different collors for there common Carrier black Rheem or Rudd Brown. Two wires that go outside use yellow blue. Yellow to Y fron Tsta and blue to common or blue,blavk or brown.or C

Need wiring diagram for a ac060x1022b air conditioning unit. i installed a relay breaker on the unit outside and need to know that i wired it correctly. took a couple of weeks to get the right part and now...


Should be three wires coming out of your box. Take the ground and connect it to the ground stud inside the unit. And then take the black and connect it to the contactor on the L1 side and then the white and connect it to the L2 side. Just match the black to black and white to white. Across the contactor.

So just to make sure I expained it good. Contactor sits just inside your case you have two small wires that are from the t-stat. Only 18 gauge. then the bottom of the contactor has two connections so power comes to the bottom side that is what you are hooking up. Now on the top you should have maybe 5 or 6 wires coming from that. But those are there already.

Ruud heat pump


Did you just install this heat pump? If so it sounds like you replace a regular a/c with a heat pump, which will require more wires for the reversing valve. First check to make sure you have 24v going to the condenser. Make sure you have a heat pump t-stat. You should have a orange t-stat wire for your reversing valve. At the t-stat you will have terminals R, Y, G, O, X or C or B, W1, and W2. R is half of your 24v circuit and is a red wire, Y is for cooling mode, G is the Fan green wire, O is for the reversing valve, orange wire, X or C or B is the other half of control circuit blue wire, W1 and W2 is the heat strips in the furnace tan and black wires. These are standard color code but remember electricity does not know colors and an installer may have used different colors. If all of this is correct possibly bad contactor.
