Responder a:Coffee not brewing but light is on.On my 4 cup Mr. Coffee, one of two thermal cutoff fuses is open. If either/both of those fuses is open, no power will reach the heating element and the water won't boil nor will the warming plate feel hot even if the power switch is lit. They can be checked with an ohmmeter/continuity tester. The thermal elements are accessible by removing the plastic cover on the bottom. I will bypass the failed fuse by wiring a new 216C/250v/10A device in parallel. All connections are crimped or spot welded so the new fuse leads will have to be wrapped around the existing leads.
Responder a:boot disk not found doesn't go awayDo you have a Windows 7 rescue disk? Can you boot this from your CD/DVD drive? Alternatively, do you have a bootable USB key? If you have another computer (laptop) running Win7 with a burner, you can make a rescue disk. Go to Control Panel\System and Security\Backup and Restore and Create a System Repair Disk on the left of the panel. Then try to boot this from your CD. You may have to review your BIOS settings to make sure this is enabled.
Responder a:Garage door closes after openingThere is an 'open force' adjustment that can be changed. Sometimes it goes out of adjustment over time as the weight of the garage door can change with humidity or moisture and/or the springs change tension especially after being replaced. Or as machead3 states, through vibration from ther drive train. The manual for this opener can be downloaded: http://www.managemylife.com/mmh/pd_downl... Reference page 13.
