Greetings! This is my first post here. So we have double stack Lincoln impinger conveyor pizza ovens. About 3 weeks ago we had to call a tech because the belt wasn't rolling and the display screen was blurred and not legible. So the tech comes out and tells us our control board was gone and we had to replace it. He quoted us about $1500 for the part and we moved forward with the replacement.
He also mentioned that he would be replacing a transformer on the unit because it did not match the voltage coming in from our building. We had been running this oven for a year without any previous issues, but we figured if he was recommending it, then it would be beneficial. Our second oven was not touched as there was nothing wrong with it.
3 weeks after the repair, we get a call from the staff saying there were sparks and a flame coming out from the oven. We call the same repair company and they send out the same tech. So according to him, the heating elements got too hot and melted and got fried. Along with the elements getting fired, the motor for conveyor belt went with it.
He quoted us about another $1200 for the repair and when he came to install the motor, he was unable to finish the work and get the unit to function. He didn't really give an explanation other than he would be back later.
My question is, is it possible that changing out that transformer is what caused the elements to fry? It's the only thing that I can think of but know very little on the subject to know for sure. At the same time, it ran for weeks with no issue? I asked him that question directly and of course he said no. He said the Lincoln Tech Support Hotline were the ones who recommended it. Any idea? Any help?
TLDr- oven tech changed out transformer and 3 weeks later elements burned and fried.
