Furnace issue

When I turn on my Suburban SF 25 furnace I can hear the unit click like it wants to work but nothing else happens like the fan doesn't come on and it doesn't fire. Any ideas as to what the problem might be?

    Look on fan housing for a circuit breaker. It should have a small red or white reset button. Verify 12 volts DC on each side of circuit breaker when unit is calling for heat.
    The fan should start as soon as the thermostat calls for heat.

    I believe the click or clicking is the ignitor attempting to light the burner. There may be air in the lines that needs to be purged or no propane in the tank. You might try turning on the stove (turn on stove gas supply for a few seconds and try to light it). If the stove doesn't light turn off the gas supply for a few seconds then turn it on again and try to light it. Once the stove fires up its sign most or all of the air is purged from the line. Then make another attempt to turn on the furnace.
