Rainbow Colors in the Oven Door Glass
My Maytag Oven Door is Rainbow Colored
When viewed under certain light sources or angles, the glass will have a green, purple, red or rainbow colored appearance. This is a normal characteristic of the oven door glass. It does not require service.
The green, purple, red or rainbow appearance in the oven door glass is due to the inner oven door glass being coated with an oxide compound. The oxide coating is a heat barrier used to reflect oven heat back into the oven which reduces heat loss and helps maintain a cooler oven door exterior.
