Another Heating Problem

[2 Sinks]

While in Virginia and the North Carolina mountains last week I found that the heater would not come on( glad we had 2 elect heaters with us).When the thermostat is switched to furnace and the slide control is moved up to turn it on all I get is the normal click,no blower motor or anything tried it many times and gave it more than enough time to time out and come on but still nothing.Have battery voltage and shore power,both tanks are full and all other gas operated appliances work fine...Any thoughts ?

Thanks,
