Hello my name is Ted i'm going to help you out today
when you say symbol on the screen can you describe it?
What type of system do you have? heat pump, boiler, furnace etc?
it appears to be an oval shape, setting on one of the small edges, with a black top on the other small edge, which makes it appear to be a bottle or bottle
ok have you replaced the batteries?
it is a furnace
here's what were going to do, I want you to turn the power to the furnace off and will need to take thermostat off the wall
but your not seeing a batterty indicator? correct?
ok this wll take a minute.
ok i'm here no worries
when I try to turn up the heat, the symbol appearl. I have tried turning it just to fan, and the fan works, on when turned back to auto it responds for a few seconds, and them turns off
ok well what were going to do is bypass the thermostat to see if it's the problem or not so once you have the power off and get thermostat off the wall I will shouw you how to bypass it to see if we can get the furnace running
ok the thermostat is off and the dust has settled
ok now you will see the thermostat wires. I need you to take the wire that's on the R terminal (usually a red wire) and the wire that's on the W terminal (usually white) and tie these together
just make sure power to furnace is off before starting this
then once you have these wires together making sure they are not touching any other wires/metal you can turn the furnace back on and let it run and see if the heat comes on.
would i need to turn off the power at the breaker box
yes or if you have a switch at the furnace itself (usually looks light a light switch)
Thank you. I am eree by myself right now, and this is a large house, causing running up and down the steps and all over, the lap top is with the others, Do you you have any other instrutions, I ca ndo this,it is just susch a run up an ddown to the tower computer just now i thank you you appear to be a patient person!
No problem no rush. Like I said once power is off and you have the R and W tied together you can turn power back on and we'll see what happens. If the thermostat is the issue the heal will go on.
If you system heats up after doing the above then your going to need to go buy another thermostat, remember if you replace the thermostat to have the power turned off while doing so.
