I have a problem with my turbopump controller that seems odd to me, but it may be obvious to those with more electronics experience. It only works immediately after being powered up when it's above 80F or so. It hasn't been a problem through the summer months, but now that it's getting colder I have to hit it with a heat gun for a few seconds to get it to start. In a room temperature environment it'll start after being powered up for 10-15 minutes. So, are there any specific electronic components that are prone to that type of behavior when they're on their way out? My other option is to go component by component and cool them off individually until it quits.
