Now what did I break?


I have an early 80's model Dou-therm furanace in a mobile home 2 wire hook up, No cooling. I don't thing there is a circut board. Furnace is clean and still in good shape. I got a Lux programable thermostat I just installed. It worked for a day and now the furnace won't fire up. The pilot is lit and I read 24 volts across the stat wires. I jumped the wires and still nothing. I'm getting my tools together. Is there a relay switch I should look for. And be able to possibly jump to test. There is power in and out of the transformer. Thanks for any words of wisdom.

Reading 24v across stat wires indicates an open. Where did you measure at the stat or the furnace
