My 3yr old Lopi Pioneer convection blower is acting strange. For a while it doesn't appear to have spinning at high speed. I did notice a few weeks back that the fan blades were somehow not able to spin freely. I gave it a nudge when the stove was off and then it worked fine. That worked for a short while and now it runs only on low speeds. Every once it a while on start-up, it will slowly gain more speed and go up to the high setting. That only works for a few hours and then goes back to its low setting. I checked the voltage and everything appears to be fine from that aspect so I know it's just the fan motor at this point. I called the dealer from which I purchased the stove and convection blowers are out of stock and on backorder from the manufacturer. Ugh.. Does anyone have the same issue or have an solution on how to fix the motor? I've looked everywhere online and cannot find any place that sells these convection blowers.
