Write appliance serial and model numbers on the user's manual or keep track of your appliances in an App or software file for repair reference
After purchasing a new appliance, write the serial and model numbers on the user's manual or keep track of your appliances in an App or software file. Then if service is ever needed, you have all the information handy to relay to the tech or repair company. I have found this especially useful as my eyes have gotten older and print seems to have gotten smaller. It also saves time as I don't have to scour or move the appliance to locate these details.
I also find it useful to include tech support or repair company telephone numbers and any repair notes with the files. Trying to track down "800" tech support numbers can sometimes be more difficult than locating the proverbial needle in the haystack.
