Whirlpool above-range microwave, model MH1160SXQ0, about a year from new: When heat rises from range below, or when microwave produces enough heat, the blower kicks on, off, on, off intermittently. Microwave may or may NOT be in use when this happens; if in use when blower kicks on, microwave immediately stops heating, (shuts off,) and flashes message to call for service. Becomes unusable until area cools down.
Appreciate your help. Claude
