Mine is a Nolting and requires a warm up also. I have a regular hand mirror and a hanging LED light that I use to check the back. I'm too old to be crawling under there...if I did, I'd have to call the fire department to extricate me! If you have a store locally that sells parts for appliance repair, check there for great lights and good prices. Those repair guys have to see into small places and they have some great products.
