I contacted Modern Appliance to fix my glass top Frigidaire Elect Oven. Before arriving I sent a picture of range. When he arrived with his tool bag on wheels and I observed he had a unsteady gait. I offered my adult son to assist him move the range forward to access the back panel Peter declined assistance. He was unable to fix the range and returning the range to the original opening he rested left side of the top glass top of range on the counter and the weight shattered the glass. Once it was broken he found several reasons why, he now requested my son's assist, the glass must have had a crack, it couldn't be fixed. No apology and he left me with a range more broken than before. Before the top was shattered he complained that some parts for manufacturers don't work because factory employees replace them with used parts.
