I bought it new four years ago. Every once in a while the oven in the
middle of cooking stops. The broiler does the same. Sometimes the
broiler or the oven refuses to start. What I mean is the gas seems to
cut off. I discovered that by disconnecting the plug from the
electrical outlet for 30 minutes or so would cure the problem. I first
tried to cut the power from the stove by throwing the circuit breaker
for a few minutes but this didn't help. Only unplugging worked.It
appeared that the problem would appear after an electrical storm so I
installed a small surge suppressor between the plug and outlet. This
seemed to help a lot because it happens only about once a month. The
electronic control according to the manual can display up to three
error messages but never does.

On those occasions when the broiler refuses to fire up, I can see a
small section in the rear of the upper burner burning so there is some
gas present. It looks to me like section is some sort of pre-burner.

It's model GLGF 377CS. Any thoughts will be appreciated. Thanks.
