Test In – Test Out

  April 13, 2013      Jeff Rosenblum

When performing a diagnostic it is important to fully diagnose the issue. Here is a way to ensure a correct diagnosis and to avoid expensive callbacks. It is called Test in, Test out. Before you replace a part, test it to make sure it does not meet or exceed the standards set forth by the manufacturer. Once the part is replaced, test it again to make sure the readings are better. For example: If an inducer is pulling .7”WC and the pressure switch closes at .5”, and is not closing, the switch would be the logical part to change. Once you replace the faulty switch, retest it to ensure the switch is closing at the specified rating. This extra test now verifies that you correctly diagnosed the problem. As always, if you need technical assistance please feel free to call one of our technical specialists.
