Hello everyone,
I bought my house a year ago and the furnace worked great all year last winter. Now, all of a sudden, it needs a tap on the left hand side of the "Johnson Control" (ignition control) to get the burners to fire up. The pilot always comes on whenever the Tstat is below room temp. I just don't get the "click, click, whoomf" that it used to do after lighting the pilot. I do have 24VAC coming from the transformer and up to the ignition control....it seems to me that it's a sticky gas valve or dirty relays inside the ignition control. Which is more likely? Or am I way off mark? It's requring harder and harder taps, and this doesn't make me feel good to be taking a hammer to my furnace. Originally this started a month ago, got it working with a light tap, and it worked fine for 1 week. Another tap and it was fine for another week, and now it's every time the furnace needs to fire up that I have to give it a whack. What's up? Thanks in advance for the help.
