turbochaz Posted November 27, 2022 Share Posted November 27, 2022 Hello all. New to this forum and I see lots of great support here. We purchased an 07 Exec back in May and have been loving it ever since. We have been using the AquaHot electric side all summer for hot water, but as winter set in, we fired up the diesel side for the first time a few weeks ago. It worked fine for a weekend but when we tried to fire it up again a few weeks later, the diesel burner won't fire. According to the previous owner, the system was serviced back in January (confirmed by date on the filter). I've done some basic troubleshooting, but before I get further into it, I wanted to ask a question here. The diesel burner status light on the panel is always illuminated regardless if I have turned on the diesel switch inside the coach. In fact even if the system is completely turned off (both electric and diesel) the diesel status light is still on. My understanding is this light should only be on when the flame exists on the diesel burner. Does this automatically mean that the photo cell is bad? Just for information, the electric side works as expected, just can't keep up in these winter temps. Any help is much appreciated and sorry for the long post.
