Just moved into new house and wanted to put contained by new programmable thermostat. Followed wiring guide and it didn't work, so I reinstalled the elderly thermostat and now the heat & a/c don't work. I checked adjectives breakers (a) the main service, condo sub-panel and outside of the unit itself. All be okay, but I recycled them just to make sure. What could be the impose and how do I go about fixing back calling tech, if at all possible?
Was it working prior to to change over? Since you just moved contained by , perhaps the previous owners turned the main shut past its sell-by date switch "off"?
Since the old thermostat didn`t work when reinstalled I would start by looking at the wires just beyond where on earth they attach to the thermostat screws. The wires are a solid copper wire and adjectives it takes is one hard bend and the lead can break inside the insulation just beyond where it is removed.
Granted this is a stretch but it happen to me once a long time ago and I`ll never forget the troubleshooting nightmare.
Also make sure that any jumpers the programmable thermostat name for are in their proper place.
All this being said assuming that you kill all power to it before switching them out. Go after the fuse mentioned above if you didn`t.
Answers: could be possible that there is a control fuse on the board that controls the heavens handler.an easy test is to remove the wires from the thermostat and connect the red and green chain together. if the fan comes on then near is something else wrong... be sure and write down on paper which wire go to each terminal on the thermostat.could also be possible that you burnt your transformer up when you connected the trial thermostat up wrong.call a reputable hvac tech and have them fix your element...
You may have shorted some wiring and cause a fuse on the circuit board to blow, if you didn't turn the power off before doing the electric wiring.
This is a low voltage fuse probably located on the circuit board. It will be like a car fuse and probably a 3 amp.
This is my best guess for something you might know how to do.
Inside the furnace, by the control board, you may hold a fuse.
It is like the fusses in a motor.
Check if it's still good.
It's easy to check, it is a plastic one, you can see the flex inside.
You may burn the fuse, if you didn't turn the furnace breaker "OF" before changing thermostat.
If this fuse is worthy, check again connections on your thermostat.
