Wall thermostat shows NO POWER, But there is power at recepticle
My GE Zoneline is not working, I operate it with a remote thermostat and have now for 2 years with out problems. It has not been needed the past few weeks and noticed last night that the unit will not operate. I've done the following checks.
1. set dip switch to ignore remote thermostat, controls on unit give no response.
2. Checked reset button on cord, it was fine, I've triped it and reset still nothing comes on.
3. varified that there is 220v at the wall outlet and there is.
How can I varify that the wall power plug is passing 220v to the unit and that it isn't defective, even though it resets fine and the test button trips the reset. I may have to call someone but prefer to check simple things first. Is there another reset with in the unit that might need to be checked or a fuse?

What is it doing now? If it works but not well it could be the postioning of the thermostat. Air flow around it must be plentiful and unobstructed. Ensure thermostat is connected to unit correctly. Using a power meter, check that you are getting power to the thermostat AND it is going back to the unit. Doesn't work if it does not send power back.
Not certain but I believe 19 is required. Where are you reading this 16.9 and take a reading from the outdoor unit WITH OUT the wire attached and see what you get. Possibly a bad wire heading inside or weak transformer.
Turn off the circuit breaker that controls the air conditioning system.
Turn the thermostat to the "On" position to make sure that all power is
cut off and the air conditioner cannot accidentally operate.
Remove the cover of the existing thermostat and remove the colored wires
from the terminals. Take out any screws that secure the thermostat to
the wall, and remove the thermostat.
Mount the new thermostat on the wall. Feed the wires through the unit,
with enough slack to allow you to make the new connections.
Connect the red wire to the thermostat terminal labeled "RH," "RC" or "R." The red wire carries the power from the transformer.
Connect the green wire to the thermostat terminal labeled "G." This controls the relay that controls the fan. Attach the yellow wire to the "Y" terminal of the thermostat. This powers the main control. Connect the white wire to the "W" terminal. This is the heating control wire.
Close the thermostat's cover and turn the breakers back on. Turn the new thermostat to the "On" position to test it and that would be all.
I hope the above helps. If it is not helpful, please let me know so that I may direct you further.....
well this is a very subjective question. How mechanically adept are you. If you know where to find the replacement OEM part, then its a mater of taking the control panel apart and replacing the wires one at a time from the old thermostat to the new one. It will have a sensor probe that will need to be routed and attached to the coil somewhere. The same place as the old one. make sure the bulb (if it has one) is not damaged. This may go without saying, but make sure the power is off first.
I don't have the book for this particular unit but, check the sequencers that control the electric heat mode, as the regulator heat pump works good. The part may have a time or temperature delay that is too long for you. Also if it has a remote thermostat, check the heat anticipate setting. You will have to check the installation manuel, but its usually .6 to .8, but I don't think that is the problem.
