I have a nine year old horizontal tappan gas furnace with electronic
ignition. I have two main issues. Bear in mind i replaced the
thermostat last year and the flame sensor.

Issue #1 The furnace won't ignite. The main blower runs (and is
problem #2 as it won't shut off) There is a steady red light on the
control board but the yellow light doesn't ever flicker. I don't hear
the other blower evaculate any gases and the igniter doesnt glow.
There is no gas odor. I have turned on and off the main power to the
furnace and nothing. I replaced the batteries in the thermostat and i
do have gas supplied as my gas water heater works fine.

Is it possible that a broken ignitor is the issue? If the igniter
doesn't work, would the system act the way its acting now? I cleared
out any cob or spider webs from the plenum and other orifices.

Issue #2 The main blower won't shut off. I have banged on the fan
limit switch housing to no avail.

Any guidance would be helpful.

THanks

Its shut down on a safety!!!! Quit screwing it, and call your fav local,
competent, licensed, insured, professionally trained, HVAC tech.
Banging on *ANYTHING* that doesn't work isn't the answer.

You need to replace the thermostat and flame sensor again.
To stop the blower you need to use a 20oz hammer. Dont use one any
bigger. Hammer on the fan/limit switch lightly and keep doing it
gradually harder until the blower stops.

Well, ya go straight to the back of the room turn left and keep going until
you
get to the ladder. Then climb the ladder and crawl out the open skylight.
After
you're out be sure to close it good and put the "Homeowner's KEEP OUT!" sign
back
up... :)
