I have two thermostats in my home.
They both worked last winter,but now only one is working.
I replaced the thermostat thinking that was the problem but it did not work.
There are two motorized valves on the furnace.By moving the lever on the botton of the valve the one that is working will ignite the furnace ,the other does not.Is this my problem?

Hello George. Welcome to the Heating and Cooling Appliance forum and the Do-It-Yourself Web Site.
Please provide more detailed information.
Kindly expound in more detail the exact problem situation with the heating unit. Also explain which type of heating unit it is.
The location of the heating unit is often times very important in determining the cause of a problem, type of heating unit it is etc.
Location Examples:
Closet, attic, basement, roof, floor, wall mounted, etc.
Brand name of the unit. {Very important}
Age of the unit, if known.
Model number and serial numbers of the unit, if available.
{Very important}
Is a fan is used to blow the heat out of registers or is the unit a radiant heater unit? {Radiant means no blower motor or fan}
Type of ignition system the unit is equipped with. Constant burning pilot flame, electronic spark ignition or glow coil ignition? {Extremely important}
What changes were made, if any, since the last time the heating unit was working properly?
{Sometimes when routine required maintenance is done, we cause a problem to develope which wasn't existing prior. Knowing what was done before the problem was discovered can help to determine the cause of a current problem.}
Examples of possible changes that may have caused the conition:
Was the Filter changed?
Was the Thermostat changed, relocated or reprogramed?
Was there an electrical power outage before the problem occurred or current problem was discovered?
Was the Gas turned off? If so WHY?
Did the Pilot just go out on it's own or did the Pilot go out as a result of work being done on the heating unit or somewhere else?
Was a part replaced on the appliance?
If so, which part or parts where replaced, who did it and why?
