Typically if you have a yellow wire in the "y" terminal blue is used as common or "c". As far as your jumper from rc to rh, that will depend upon what type of heat you have. If all of your heat and cooling come from your packaged unit outside, yes you will need the jumper. If this does not work maybe you have a bad breaker or transfomer.

SOURCE: Replaced thermostat on FA4ANF030 with Honeywell model rth3100c does not work

4-wire typical wiring of a thermostat is: Y (Yellow) G (Green) W (white) and R (red). Inspect the thermostat to see if it has a jumper from R1 to R2. If not, put your red wire on R2. On a 5-wire thermostat you may have a blue wire. This will go to the common terminal (usually C but sometimes B) check the inline fuse in the air handler to see if it has blown. Replace it only after wiring the thermostat correctly.

Thermostat not running furnace properly


Assuming that particular thermostat has a common mercury switch, the wiring behind or just inside the unit may be causing a strong enough magnetic field to throw off the balance of the mercury (liquid metal). The same scenario could be caused by other wiring or devices near the thermostat.
To test this theory, hold a compass as near as possible to the thermostat and wait it to come on automatically. If the needle moves when the switch engages, the magnetic field is strong enough the throw the balance off.


When tucking-in the wires for the thermostat, avoid winding the wires in a spiral or wrapping them around anything. An active current through wrapped or winding wires will create an electromagnetic field.

Honeywell thermostat short and then went blank by mistake i short the thermostat with a wire and then became blank


Check the transformer in the air conditioner/heater. There should be a fuse on teh 24 volt side. Shut power off to the furnace. Locate and check the fuse. If there is no fuse, you probably destroyed the transformer.

Make sure red wire is on R terminal, white wire is on W terminal. Also look for a short in the thermostat wire.

The digital display is not functioning


the thermostat could be bad. It may have gone bad on its own or due to a short in the supply wiring. Sometimes mice will chew on the wiring in the wall that leads to the thermostat. But I wouls change the thermostat. They do go bad. Make sure you turn the inside unit off first in case you accidently touch wires together. This will blow the transformer inside the unit if the fuse doesn't blow first. I even scene thermostats with fuses inside. So you may want to take the thermostat apart and check for inside fuse also.

My Honeywell T87F Thermostat doesn't shut the A/C off when the temp in the room gets down to the Thermostat setting. I have it set on COOL and AUTO. I have to shut the A/C off; then later turn it back on...


Remove the thermostat and disconnect the r and y connection. If the A/C continues to run ya got a short in the wiring somewhere. If it shuts down then your tstat is hooped.

Honeywell 5+2 day programmable thermostat will keep heating to 29 degrees!


Is sounds like you wired it correctly, The black is a little unusual perhaps its blue, anyway, try disconnecting the wires from the thermostat and see if it shuts off. If so, then it may need to re calibrated. I will need some more info to help you anymore.
