A customer has Thermador T30IF70NSP freezer no cold. This is a standalone built-in unit. Freezer stop produced cold and also icemaker stopped working. Customer cold us after having 2 other companies came to his place and refuse to service this unit. Thermador tower units are very complicated in terms of the number of electronics involving in the cooling process. These units require special knowledge of Thermador documentation and specs.
We conducted several tests and find the few problems. The customer never did the maintenance for this unit. As a result duct block airflow on the condenser fan motor. At some point, condenser fan stopped working. Because of that conditions compressor overheated and damaged himself. I recommended replacing the compressor, dryer filter, and recharge system with freon. A client gave me permission to proceed with the repair and I ordered the parts.
The unit needs to be uninstalled from the cabinet for the compressor replacement. But I found the way to reach all necessary components and do all welding from the front. First of all, this method not only saves lots of time and labor for me it also saves additional spendings from the client. In some instances like this one client had two units hooked up together, which means instead of uninstalling one unit you have to remove both units. These units are very heavy and required two people to remove them from the cabinet without damaging the floor or cabinet. That’s why I found the method to conduct similar repairs from the front.
First I removed all components which were blocking my way t the compressor. After I cut the old one and replace it with the new one. After I replaced dryer filter and welded all copper tubing connections. It is time to fill up the system with the proper portion of freon now. As soon as I had exposed area below the freezer I replaced the condenser fan motor. I conducted manual icemaker test. Icemaker passed all tests and was OK. The reason for stop producing ice was too high temperature inside the freezer. Because of that I recommended to the client just wait 48 hours after repair and after it will start producing the ice. Finally, I run built-in self-diagnostic software to make sure the unit runs as intended.
Another Happy customer!
