Within a month of buying my Mt Vernon AE insert, the control panel went blank. Quadrafire sent me a new one. Now in my third winter, the control panel went blank again. I spoke with the company and feel their must be a defect if it keeps going blank. They won't replace it and will only warranty a new one for three months. The dealer I bought my unit from went out of business. Any suggestions on where to buy? Anyone else with the same repeated problem? Thanks.
