In my last post I mentioned that I might be getting some solar heating.\u00a0 I had checked my fan to make sure it was turning and found that it was stuck.\u00a0 A small push got it turning again.\u00a0 However my QC checks still showed signs of solar heating during the daytime.\u00a0 Then I started seeing elevated temperature readings at night as well.\u00a0 I suspected the fan bearing had seized causing the fan to get hot and be the source of the erroneous temperature readings.\u00a0 So I made some time to go outside, take the solar shield apart and see what was going on.<\/p>\n
The first thing I did was listen for the fan running.\u00a0 No fan was heard.\u00a0 Then I put my hand up inside the solar shield to check the fan wiring to see if it had come loose.\u00a0 My hand brushed up against something that I didn’t recognize.\u00a0 I bent down and looked up inside the solar shield to find a small wasp next.\u00a0 Luckily it appeared it be deserted, otherwise I would most likely have been stung.\u00a0 I knocked down the nest and started taking the solar shield apart.\u00a0 A few wasps flew out and i jumped back.\u00a0 When the coast was clear I carefully started opening up the solar shield and peeked inside.\u00a0 I saw a larger wasp nest and several wasps flew out toward my face.\u00a0 I backed up as fast as I could move in preparation to run away.\u00a0 I ended up falling over backwards and slightly injuring myself.\u00a0 Luckily the wasps let me escape without stinging me.\u00a0 I got a can of bug spray put of the garage and that was the end of the wasp nest.<\/p>\n
I was now able to complete my dis assembly and confirm that the fan had failed.\u00a0 I ordered a new fan, which took about a week to receive.\u00a0 Then I removed the old fan and wired in the replacement.\u00a0 The old fan was pretty hot when I pulled it out, so I feel pretty confident that ti was the source of my heating.\u00a0 The station appears to be working so I plan to let it run for a day or two and keep an eye on my QC checks.\u00a0 I also have a spare fan (I bought two) so I can make repairs faster when I have this problem again.<\/p>\n
