I have a Honeywell thermostat non programmable one, just heat and cold, the face was blank and I replaced the batteries, and nothing is happening, there is nothing showing on the face. What else can

SOURCE: my heat is turning on

This is not a PC problem
Symptom
Heating comes on, but sometimes it
gets too hot, sometimes too cold.
Neutral not connected
Cure
Check wiring in room thermostat. Look for a
connection to the Neutral terminal (N 2 on
the Honeywell T6060, T6160, and T6360).
Make sure that it is connected (check
continuity).
If there is no neutral available, replace with a
two-wire thermostat, e.g., CT200, CM61 or
CM67. These will also offer extra energy
savings, (Without a neutral connection, the anticipator within the room thermostat does not work,
so the temperature control reduces from ± ½ºC to ±3ºC. People can feel a six degree
temperature swing. Then, if they try to adjust the room thermostat to overcome the
problem, the temperature swings become even worse.)

SOURCE: cold air will not turn on

This problem of yours should be handle by a professional on heater/cooler trying to repair it by yourself will just cause more damage because you should have a knowledge about this device so better ask a repir guy or take it to a repair center near you to avoid any problem with it...

Good luck.......

try to get one that is made for oil heat, the installation is easy only two wires, and the instructions make it easy.

I am a honeywell dealer and this stat is obsolete and no longer supported. I am not able to pull any info on this. It might be time for a new one.

SOURCE: Honeywell dial theromostat.

you need to check the furnace itself for , locate the 24 volt ac transformer inside the unit and see if it is fused some are some not , check to see if you have 120 volt ac in from the source and 24 volt ac out , sounds to me as if you have lost the 24 volts ac which powers the thermostat as well as the furnace pay close attention as to how you remove the wires and make a diagram and you should be able to replace it yourself , once you get it uot goto a heating supply place in your area and let them match it up and this should be a fix ya
