Ok....Getting a vacuum switch error. I have done the following: 1. Cleaned entire unit top to bottom including blower and exhaust 2. Check and blew out vacuum hose 3. Jumped the switch...unit worked. 4. Replaced the switch with a new switch.....no workie 5. Said a few really bad words. 6. Checked for leaks...none apparent. Any and all suggestions would greatly be appreciated. Very frustrated!!
