Hello. My name is XXXXX XXXXX do my best to answer your question.Remember, you are not charged and I am not paid until you accept my answer.
The front usually snaps off
Sometimes it is necessary to take something similar to a butter knife to seperate the front from the sub basae. Do you know the model on the thermostat?
Tim,How? I don't want to break it? Also, to get the display back will I need to remove the cover?
You should be able to grasp the sides and pull straight out.The front plugs into the subbase
I do not know the model but will try the butter knife. Once I get the cover off, what do I do to get the display working?
Most Totalines have two batteries inside that need to be replaced annualy
Can you upload a picture here ? I will try to identify which one you have if so
I have the cover off.MOdel is P474-1050
Ok let me grab a manual
OK looks like the P474-1050 does not use batteries. Your issue is going to be not getting power from your air handler to the thermostat.You will need to check to find where you are losing voltage.What is the model on the heat/cool unit?
Looking it upIs this a split system with indoor and outdoor unit?
Outdoor Unit. Something in the attic?
I see that is the outdoor section
In the attic is going to be an air handler
We need to make sure power (breakeer is on to the air handler). Have you checked all double pole circuit breakers
Are you able to go in attic and check a few things? And do you have a volt meter to verfiy voltage?
It would take a lot for me to get into the attic, plus I do not have a volt meter. The double pole circuit breakers I assume are in the main breaker box? All looked ok and I reset all. What next Tim?
First make sure breaker to air handler is on.After that it will be necessary to get to the unit in the attic.Then check to see if there might be water in safety pan and if so, there may be a float switch breaking circuit. Then tou will need to get a volt meter to continue trouble shooting.Next, You will need to open panel on furnace,verify power to air handler with volt meter,If power there, check for auto type fuse to see if it might be blown. Next we will need to check the transformer to see if there is power in and power out of transformer.
Ok. I am not equiped to do these things? Is there a recommendation in my area of St George Utah to call on someone? Would any AC company be able to troubleshoot?
Any a/c company can do. I am in South Alabama. A bit too far for a service call(lol). Seriously though, any licensed ac company can do
Ok Tim. I will follow-up tomoorw beginning with your last suggestions. Thx and I'l accept the reponses/help. Anything else I should know before hitting "Accept" and ending the session?
You can check the drain pan(float swicth) and the auto fuse in air handler without a meter, but you will still need to get to the unit in attic to do so
Ok Tim. Understood. Anything else?
