PE Vista Insert - Blower Not Working

[Jim Ignatowski]

Hi Everyone - Hoping someone can provide some advice. I have a Pacific Energy Vista Insert Series: D - probably about 14 years old. It gets a ton of use, it runs almost continuously from late October to May. Unfortunately this afternoon, the blower is no longer working. The insert has a thermostatic controlled mode and manual mode - In either position I can hear a slight hum indicating power to the unit. I tried vacuuming areas that are accessible - the fan had gotten louder over the years but the housing had taken a few hits a lot of the noise was caused by vibration. I can't figure out how to get into the unit and was hoping someone could provide some advice on how I can begin to troubleshoot. Attaching a couple pics - any thoughts would be appreciated. Thank you
