My electronic board does not work anymore in my older style purchased (2010) SM260. Replaced the probe, did my trick of spraying the electronic board with electronic cleaner, but it didn't work this time. Also had replaced the thermostat prob as well. Just won't read temps correctly anymore. Does anybody have an old sm260 electronic board I could purchase from you. The upgraded unit is $1600 so trying to avoid that if possible. Thanks for any help one can give.
