Goodman thermostats 1c26-179

I live in a condo that is 1 of 4 in our building.  I have two zones for my ac/heat that are separate of each other.  There is one furnace that controls all the units downstairs for heat and hot water.  If there is a problem with the entire building, the management company pays, if it has to do with our unit only, we do.  This is important to know because I am unsure of what is causing the problem and who is responsible to fix it.  Both my units no longer work correctly.  Our upstairs unit (A) stopped working altogether and the management company sent a professional to fix it.  It was discovered that it was heating up, just not getting the water to make it work.  It was fixed, downstairs (I'm not sure what this means) but the problem was not in our unit.  The heat came on and worked for several hours correctly.  Then, the auto mode no longer worked.  I can turn the heat on by turning the thermostat up high and letting it run until warm enough, and then I manually shut it off. At this point I was told the issue was now my problem, i.e. I have to pay an electrician to come out.  We have made do for the time being because of finances.  This all began about 4 weeks ago.  Today, my second unit (B) is causing problems.  It appears to be confused about which mode it is in.  To make sure the heat works, I must turn the temperature down like I was running the AC.  The auto switch also seems to not be working properly.  I called the management company who is convinced the problem has to do with the thermostats themselves believing it a coincidence that I am having problems with two separate units at the same time.  I would like to use an electrician as a last resort since money is tight.  I also want to feel satisfied that the problem is not the responsibility of the management company before I reach for the checkbook.  And, if I can replace a simple part myself, I'd prefer to go that route.

    Thank you, this is encouraging.  I've started to search for the part and haven't found it yet (though I've just started to look).  What if I can't find the exact model?

    I'm not sure, though I know it is controlled by hot water down in our basement.  Does this tell you anything?

The problems you are describing do sound like thermostat. These are simple to change as long as you get exactly the same thermostat as a replacement. That way you simply put the wires on the same screws as they were on the original thermostat.

How to hook second thermostat ?

You can only do this if the heating system is set up with separate zones. Example - A separate thermostat for each apartment. Heat only goes to one apartment at a time with each thermostat. You cannot connect two thermostats in one zone.

Replacing a Honeywell T822l1000 thermostat.

The W terminal is used for heating and goes to a small electric valve in the water line to your baseboard. The Y terminal is for a cooling system. The T822 is wired wrong and is not working. The wiring between R and W is corect for a heating only application. The R terminal is the power source.

Hi, start at the thermostat on this unit if nothing else has been done as far as trouble shooting and repairs. 3 months doesn't mean a thing when it comes to a/c and refrigeration & heating parts. Check the stat operation, or replace it, and I am 99.9% sure this will solve your control problems.
Sincerely, and a good day to you!

I would like to know the specifications of my Goodman model CPKE42-18 AC/Heat pump system. BTUs heating and cooling? Thank You,

Many HVAC people talk in tonnage. One ton is equal to 12,000 Btus. Therefore your model specifies your cooling tonnage at 3 and 1\2 tons. Your heating would be determined by how many if any supllimentary heat strips are added. If you live in Anahiem or Miami that's not really important. But if you live anywhere that gets down into the 40's at night you'll want strips. Cooling wise depending on where you live and what your insulation is like, I'd say your unit is good for 1100-1300 Sq feet of living space.

Goodman PC060-1B Package AC...Need Wiring Help

Depending on the size of your Electric heat you can use one set of wires because your unit does not run with the heat like the heat pump. The large set of wires going to the electric heat should be used. You may have to jumper a new set to the contactor. On Goodman unit come in L1 and L2 jumper to contactor. Very simple good luck. Rus

No heat through vents

Does your condo have more than one thermostat? if so there are powered dampers that open and close to direct heat where it's being called for. You may have dampers stuck/inoperative.

Goodman with 2 thermostats, freezes in summer, no heat in winter

is the system zoned? if so maybe the zoning control board to the damper motor is wired improperly. when a system freezez its because of 1- restricted air flow across coil, (maybe dirty filter) or 2-low refrigerant charge. again could depend on how its zoned.

Hello brandaleepup,
Your problem may be at the furnace control end and not your thermostat. To determine that, simply unhook the two wires from your thermostat so that they do not make contact. When they are electrically opened like that, your furnace should shut down. If it doesn't, then the problem is at the furnace control board. You may have a relay that is staying on even when power to it is disabled.
Hope that helps...
