My heater stopped working I have a gas furnace (central heating and A/C). The thermostat timer is not moving. There appears to be no power at the thermostat. The fan will not come on either. Any suggestions?

check for power at the furnace.... does your thermostat use a battery?

in side the furnace there is a control box or board that has the Thermostat wires ...remove the red one and jump R & W with a seperate jumper there also might be a door safty switch.... make sure this is pushed in... If the furnace starts, it in the T-stat wiring or the t-Stat...if it doesnt start, you either have a low power problem or a line voltage problem... both of theses problems you need to know how to use your multi meter and read a wiring diagram
