I have a Lennox G26Q4/5-125-3 heater serial# 5897M22940. I turned on the heater and it worked for a few days. This morning I noticed that the large fan below would not kick in. The small black fan made a strange noise so I removed it and dumped a little bit of water out and re-installed it. The heater then worked fine. So, I would like to fix this problem so that I don't have to empty my fan every morning. What part would I need to purchase. Thank you.
Check all of the drains lines and the ports on the cold header box and make sure they are not plugged.
