I had problems with my board just after warranty expired. Got a new warranty board free.
Never returned the old one
I then bought some replacement parts. Have yet to need them. Going on about 8 yrs since new
Good idea to have in stock. Check with seller to
confirm correct resistance.
My brother suffered a similar failure.
Good luck.http://www.ebay.com/itm/Harman-Coal-Pel ... 1c39a0e8ff
