Hi, I have an old (early 80s) thermostat in a not very accessible spot. Can't remember how to open it to replace the batteries, and don't want to force it. It's a dual setback model that was top of the line at the time. Any ideas? I know it's hinged somewhere, but can't really see where, and I remember it's somehow a little surprising . . . just can't for the life of me remember how. I sort of faked the category in hopes that it would come close.

If you replace the battery in time, the furnace should still work. You didn't mention what type thermostat you have, but the battery is located inside the thermostat housing. Most can be accessed my opening the flip down cover of the front of the thermostat (this where you generally program it). Inside you will either see instructions for replacing the battery or you will see another small compartment door with a battery icon on it or it says "Battery". If none of that appears as stated, the batter will be behind the thermostat housing. It's generally 1 AA Battery.
16 yrs old? Im guesing this is a hot water heater.Not a air conditioner.
If its still making hot water you may not need to replace the whole unit.
The valve that is leaking is a high pressur relief valve and they do go bad the sprigs become weak over time and some corrosion may not allow the valve to seat properly.
1st step is to shut off all incoming and out going water to the tank.
2nd Shut off fuel or gas to the unit, and annonce to everyone your are working on the hot water heater.
3rd at the very bottom should be a drain valve much like a hose spicket,open this slowly and drain the tank,remember the water will be hot.You may not need to drain it all the way,while draining pop open the relief valve,when you stop getting water from it,you are below it and can turn the drain valve off.
4th remove old relief valve and replace with a new one,i think they are rated at 15 psi or 30 psi blowoff pressure,hopefully there is a tag on it with that info.
When you go to install your new one use some pipe thread compound or teflon tape around the threads before you reinstall valve.
Once done slowly refill tank with water, check for leaks.When full open up hot water valve to house and relight buner.open a faucet in kitchen to hot to bleed off any air.
sounds like that thermostat has reached the end of the road. My advice is to replace the thermostat because its 6yrs old and is worn out due to continued use. programmable t-stats have a wide price range to meet your needs. and the batteries in a thermostat are only for back-up power because the thermostat runs off of a 24volt power supply from the air handler.
The cover on your thermostat should snap off pretty easily by pulling gently on lower right corner.Remember to not force it,if it does not open you can try one of the other corners. Under the cover there will be either abattery comparment or if it's 9 volt just two wire connector.Replace battery with same size type number and put cover back on.The battery is normally used to keep digital controls working,clock setback times etc. Hope this helps. Thanks
Hello my name is Heath it will be my pleasure to assit you. If you did not turn the power off to the furnace before rerplacing the thermostat then you may have burned out the board in the furnace. But first if there is a RH/Rc terminal in the new thermostat then try removing the jumper between the two and see if the thermostat will operate properly.
the unit has a split line where to top meets the base plate pull on the bottom side with your fingernails at the split line and it will pop free it will take some force batteries are accessable after that, just line up and push to reinstall
