Unfortunately No. There can be up to a dozen different reasons why the symptoms occur. Without being able to diagnose the appliance, using our knowledge, experience and test equipment, all we can do is guess. Many companies will quote an approximate price over the phone (usually low enough to attract your attention) and when their people arrive you find out that the repair is more than you were quoted over the phone, based on what they find, and you are still responsible for the service charge.
