Thermador Mod prds366us
Two burners on the left side of the cook top have XLO on knob. When knob is in this position the solenoid drops out and no flame. Both burners do the same thing. Is this normal ? Owner not happy about it.
Oven will not maintain set temperature. Heat indicator light is on but no rise in temperature. Suspect bad thermstat but don't know how to get top off the range to change out the sensing bulb.
