Furnace wil, not ignite when calling for heat

For this answer, we need a model and serial number.
Generally, be sure the power is on, does the heat moving device run? (Fan for air, or pumps for water)

Miller furnace says pressure switch is open

you have a bad VPS-Vent Pressure Switch- it monitors oxygen and gas mixture to allow furnace to fire up-- you can get part at a local Heating and AC supply house just call and give model and possibly serial number and they can tell you if they have the part and cost.

Where is the reset button for gas furnace serial # MGH9301-02963

Normally there are no reset buttons on most furnaces. There are two burner rollout switches, those are the only manual reset buttons on the furnace.

To reset your furnace, turn off the fuse or breaker to the furnace, wait a few minutes and the fualt will be restored. If the furnace tries to start 3 times and does the exact same thing, then you have problems

Is it cost effective to replace draft inducer blower on 22 year old furnace?

Depends on the cost to repair. Probably a 22 year old furnace is not very efficient also. Take every thing into consideration.
If it still works it may work for a while but you don't want a break down in the middle of winter.

Coleman gas furnace. Burner will re-fire for a few seconds during the cooldown. Model G8C07512MUB12A

This is a little complicated because it can be several things and you need to provide more specific info....It could be your furnace is shutting off on the High Limit...which means your furnace is running too hot...check the filter , return air vents etc would be an airflow problem...dirty blower....Furnace can be too big for your house....when the furnace shuts off on High LImit , the fan will continue to blow air , cooling it down as usual and once the furnace cools enough to reset the high limit trhe furnace will Ignite again as long as the thermostat is still calling for heat . The furnace could also be running too long and getting too hot....your Ductwork can be too small...many factors come into play
