Ok John this means the Humidity sensor has failed, this is not a good DIY repair since the unit holds lethal voltage even when unplugged.

If after the warning I have given you decide to do the repair yourself you would need to access the inside of the unit to get to the humidity sensor.

Is replacement of the humidity sensor something that can be done easily at reasonable cost by an appliance repair service? Or should we simply replace this ten year old microwave oven? What would you advise.
It would cost around $150 to take the unit to a repair shop, Bearing in mind a new unit would cost around $229 I would not put the money into the old microwave.
