This example site is good for what it is; appliances,
http://www.applianceblog.com/mainforums/forum38/
but there are Forums out there that will address whatever problems you have with your out-of service, or intermittent problem with your widget.
There are many I have found, computer, HVAC, Inverter, Washer-dryer, you name it. Helpful if you want to repair it, need additional information to decide on repair or replacement, or just want to know more about it.
Just play around with your search engine; How to fix my trace Inverter... Took me to a boating Forum and they had a suggestion for a 'Hard Boot' with a load on it, to clear the memory of the operating circuit board. Another site showed how to run a diagnostic on an appliance.
Good stuff.
