I have an old (35 year) furnace. I turned the gas main and shut the furnace off over the summer. Yesterday, I tried to relightening it with the instructions on the front panel, however failed (a few times). I simply noticed that there was no gas coming out at all, though the gas main and the thermostate are on. I wander anybody has any idea what could went wrong? I don't even know to who I should contact since the furnace is quite old that the original producer may have gone on the earth!
Any information and help would be appreciated to send to my email.
