Go to the thermostat and switch the fan to "ON", if the fan runs you have both high and low, 24 volt control voltages, go to the unit and look for a flashing code by the blower assembly, there will be a tiny port to see through on the lower door of the furnace, this will give you any codes telling you what has failed.

Sounds like it needs cleaned. When the burners get dirty they don't light as they should and gas builds up to give you a mini explosion during start up. The burners should be removed and cleaned.

Need furnace model number. It sounds like you're looking for a standing pilot. Your furnace might not have one. Very likely to have a spark ignition type system or hot surface igniter.

This happens when the furnaces tries to light to many times and doesnt succeed. If you stand in front of the furnace while it is coming on, you will be able to hear the problem. If its an electronic start, there will be a clicking sound, followed by the gas valve opening to start it. If it has a pilot light, make sure it is lit, then listen for the gas to come out, it will make a hissing sound. If no gas is coming out, first double check to see if the gas is turned on to the unit, if it is, then its possibly the gas valve. Oh, if it is electronic, and you hear gas, but dont see a glow inside the furnace, or no glow or gas, it could be the ignite. Hope this helps.
