model # DSS25MSSESS lights in the to not working. Tested with a tester and no power. Changed light bulbs still not working. Took off unit where light bulbs fit . Disconnected harness and tested is power going to the harness assembly. Yes power there. Is it possible the harness assembly has a problem. Please let me know . I thank you in this matter.
Answer Dave, Yes, it is possible to have a "weak" or loose connection in a harness. Based on your post, you have voltage, to the harness, But if there's a weak or loose connection, when the light illuminates, the voltage won't pass the weak connection and voltage disappears, theres not enough of a connection to "carry the load" 120 VAC to illuminate the light bulb.
