Did Sanyo make Burnham Mini Split Cooling Unit?

They were disposalable then and as is now 15 years and to the thrash pile they go unless you have extra money to throw at some thing never meant to last more than 15 years like window shaker . Depending on what is needed it may not be worth it to have repaired unless some very basic other get it replaced w a Mitz ,best tech service and plenty of easily read on line service manuals with all the info they provide if one cannot figure what the issue is they should not be working on them . Another note proper diagnose and repair is never cheap being it usually takes at least 10 years in the field to become half good w proper training and mentors unless a Mensa grad . On a another note if Sanyo leads to no end look at EMI units I believe the manufactured and where possibly rebranded not bad stuff and plenty of it was sold durning there time I think parts may still available at least a few years ago they where another would possibly be Panasonic and other then that who knows
Peace and good luck clammy
