Ok. Here goes. A few weeks ago I had some trouble with our heater. It wouldn't light. The man came and fixed it. There was a wasp inside it and stopping it from working. Everything was put back together. Everything was working fine. Used it Friday night to test for a while. Worked fine. Thought I'd just take the early morning chill off the air on Sat morn. Wrong. Not working anymore. All other gas appliances work fine. I think it is a 3000 model.
Any suggestions?
