Did you know that you can usually get copies of owner's manual on-line and download them to your computer or copy/email them for your customers?
Just go to the manufacturer's website (I'll have some listed below) and look for the tab for Customer Service or Support. There should be a tab under that for manuals. You will need to have the model number of the appliance. Then just download the PDF file to your computer.
Consumers: This would also be a good time to make a file for each of your appliances and load the necessary information for each appliance (Brand, model number, serial number, date of purchase and scan in the warranty info, receipts, service calls, repair company, etc). Wow! Don't you feel organized now?
Servicers: You can also add these to your computer files for your customers.
Also, sometimes accessory items (stack kits, conversion kits, dryer racks, etc.) are listed in the owner's manual; some of these are not listed in the parts lists.
Have a great week!
