Here we are 5 years after your posts & I'm finding myself in the same boat you were in then.
Have you all been successful in repairing your fireplace blowers, thermostats, etc.? If so, what did you do? Is there a "how to video" or someone to contact that might be able to help.
I did try calling & emailing Dimplex,.... waiting for a reply. Thought it might be faster to ask the experts who've been through this.
Any pointers are greatly appreciated.
