After paying a local stove company $500 to fix my stove and got it home and was doing the same thing (shutting down after 20-30 minutes), I returned it and asked for my money back and they put my old parts back on. I investigated and found the electronic eye barely visible. Got it cleaned but still opaque so I'd like to buy a kit. Tried www.woodheatstoves.com and they were awful. Paypal ordered them to refund me when they send the wrong part. I'm having my chimney cleaned and everything cleaned. Wondering if it could also need a new control panel. Can't see the serial number because it was removed! Can anybody help me? Thankyou. I'm a petite DIYer!
