-I have a Jenn-Air microwave model M437W-04 I tried to replace a blown bulb that was broken in the socket. The bulb broke away from the base and trying to disengage bent the housing. I put a new bulb in as best I could and the circuit breaker tripped. I turned the power back on and the bulb along with the fan do not work. I looked for a fuse but found none, except 240 volt one. The microwave works but the fan and light do not. I also checked and theres is no power at the connection for the light and fan. Can you help me?
