Hampton Bay 120 Watt Transformer Manual

This is the second Hampton Bay transformer that I purchased to replace old ones(not Hampton Bay) that had worn out. They are so easy to install and maintain. I've had the first one about 2 years and never touch it, except to change the number of hours the lights are on and I.

After several years with no issue, mine started the dreaded E1 error. But if I pressed up or down arrow, the transformer came on and ran fine for the rest of the night. So it wasn't caused by the load (length of cable or current draw) or a ground fault.
I took the case apart (6 screws). Inside is a small 'controller' in a plastic case. The case has 2 screws holding it to the backplane metal. Removing it, the case has 4 small screws on the back holding the cover on. Removing the cover, there is a circuit board with some chips, diodes, resistors, and capacitors. The smaller 'can' style capacitors looked OK (you can usually tell when they are shot because they swell up or burst). The biggest cap (redish-orange color mounted horizontallt) is a different type - a metalized film capacitor. I de-soldered it and tested - sure enough - bad. Markings said CL21 305J 250V. Checked on ebay and found the closest rated one - actually a little higher rated (335J 250V CL21) cost $2.99 for 2 of them plus $1.99 shipping. It came about 2 wks ago and once soldered-in and reassembled. It fixed the problem. Unit is now like new.
So, that E-1 can indicate other types of failures besides those listed here. The odd behavior with mine being that the initial start-up failed (after working for years), but a press of the buttons cleared the E-1, indicated to me that it was failing inside the start-up logic.
Since it was effectively useless to me, I wasn't concerned about the risk of takling it apart to see what could be wrong. Glad I did, because I really liked this power supply.
