I was not completely satisfied with the repair/diagnostics agent who was paid to diagnose the issue. He did not pull the offending part out to show me the damage. He did not remove the item and put an electrical tester on it to confirm continuity of the heat pump either. I did pay a reasonable amount of money for the service and thought a 5 minute visual inspection was not good enough. The technician was on time and friendly though and assured me he had seen this all before. We were offered a discount on a replacement machine though which we were not expecting.
