I have a mobile home furnace Intertherm #1378. The pilot light is on, but the burner will not light. The thermostat clicks on and everything seems to be running properly, but there is no flame. Last year I had the motor replaced and the relay switch. What could be wrong? Is there a gas valve that is not opening properly

First make sure that the gas valve is in the on position. There is a spring load diaphragm that will stick when not in use over time, When the t-stat clicks on for heat tap the valve with a hammer LIGHTLY. If it doesn't come on replace the valve.
