SOURCE: Thermostat unit not cooling house.

Okay. Here's what I suspect in order of probability:

- low refrigerant charge
- contactor not getting 24 volts from controller (controller problem)
- bad contactor
- bad capcitor

I'd start with the charge, as suggested by mastatech. But if it is low, you'll need a service call, anyway, so pressing the needle valve may not be necessary.

I'm assuming you're not going to be taking the unit apart and testing stuff, so you'd need a service call for that as well.

I guess bottom line is, call for service. At least, I think we've ruled out simple stuff which will avoid paying for a service tech to come out and flip a switch.

Maybe mastatech has some other recommendations.

SOURCE: Can not figure out how to control thermostat

If you take off the front control panel cover (simply prying off on the edge with finger) you will find 2 small buttons under the display panel, one being mode and the other being prog.

Press both simultaneously and hold down for 5 secs and the display will blink, press prog to advance to what you want to program, kinda like setting a timex watch. As I recall you can set degrees celcius or farenhight/ cycle/Hi/Lo etc.

Just keep in mind when you set using the up and down arrows:

flashing H means: at what temp do you want HEAT to kick in?

flashing C means: at what temp do you want AC (if you have it) to kick in....if no A/C fan simply blows air.

Hope that helps.

Break down of thermastate housing


the thermostat housing holds the thermostat in place. It is covered by a cap( a couple of bolts holding to the engine block. Also supports the temp. sending unit. The cap is connected to the upper radiator hose ( feeds coolant to the engine. Very simple, Remove the hose, unbolt the cap, clean the cap and housing of old gasket down to shiny metal, remove and replace the thermostat, place new gasket, bolt the cap down, reattach the radiator hose, and start the car to check for leaks, let it warm up to make sure thermostat opens. You can do this in 30 minutes. a ratchet, short extension, sockets, flat tip screwdriver, extra coolant(maybe), and a scraper. that is all the tools you need, when you get the thermostat, make sure it comes with the gasket(some don't). hope this helps

Engine not coming up to temp. Looks like a simple job to replace the thermostat. Is it as easy as it looks


Yes, it is a relatively simple job. Make sure you replace your coolant temp sensor at the same time, these usually go out relatively soon after the thermostat. The coolant sensor should have a crush ring under it. Also clean out the thermostat housing if your reusing it, use brake clean or hot soapy water, rinse and dry. Hope this helps!

I have never used central ac before - how do I set it? If it is on 75 will that cool the house? If I want it cooler, do I put it lower? like 65?


As to your question 'will 75 cool the house?' The answer is 'yes' - if the outside temperature is low enough. Typically speaking you can expect your central AC to cool a properly insulated house to a down to a temperature of about 20-25 degrees lower than the outside temperature. For example - if the outside temp is 95 degrees. You could expect to get your house down to 70-75 degrees. If the outside temp is 110 degrees then you could only expect to get the house to 85 or 90 degrees.

So .. as you can see - your 'inside' temp will be directly affected by the 'outside' temperature.

As to the operation of central air; it is very simple.

I would suggest that you not pay 'too much attention' to what you have the thermostat set on. A comfortable temperature - is a personal thing - so - I would set it somewhere - say 72 and see how I (and others in the house) was handling that setting.

If you want it 'cooler' just 'notch' it down a degree or two - if you need it a little warmer - turn it up a degree or two. Do this "fine adjusting" till you have the temperature setting you are comfortable with.

Usually the more you can leave your thermostat alone the better off you will be from a comfort position and an electrical useage standpoint. Obviously, the higher you have your thermostat set the 'less' it will cost you on your electric bill.

How high you set the temperature is a balance you have to come to based on how comfortable you want to be - matched with how much you want to hold down the electric bill.

hope this helps

Can't get my Simple Comfort 7890-DHW thermostat to set on heat. Tried the mode/program and have made it worse.


Push up or down arrow once. H will flash, this is heat setting. Set your temp. Then C will flash, this cool temp. Set your cool temp. After short delay stat will go back to display room temp. Red light heat is on. Green light cool is on. Hope that helps
