Hello,
I have been struggling with my direct vent 8160 Luno hearthstone fireplace for the past few weeks now. The issue is the home is over 200 miles away and I have renters coming, so I really need to get the only heating source up and running. This is my third trip in 2 weeks to try and solve this so I want to be thorough and make this my last one.
Current Issue
The Nest still has power and says it is heating, but the fireplace isn't lighting. For a while it was lighting perfectly, then it slowly started turning on and off randomly. Now it just won't turn on. I had a service guy come when it was running decently and he says the thermocouple and thermopile are fine, but they are a few years old at this point. Pilot light never goes out.
Setup
The old set up was a 750ma/24vac transformer to Packard pr380 fan relay that ran to the Nest. That worked for a about a year, then didn't. I replaced the relay and it stopped working quickly after. I then installed the Honeywell R88445u1003 box and that worked for a few days and now it isn't.

Plan
I am going to drive up perform the following:
- Replace Nest with another Nest (warrantied)
- Clean out inside of fireplace (check the vents and holes for blockages)
- Replace thermopile
- Check the honeywell box and ensure it is wired correctly and the fuses and transformers are ok?
- I think there is a chance I crossed the th/tp connections on the honeywell box. Would that make a difference? It obviously worked for a while so I feel like no.
- Should I check for wire shortages? The nest recognizes the RH, W1 and C wire so I feel like that isn't it.
- What else could I possibly be missing?
Thanks!
