Question about Intermatic Programmable 7 Day Digital Outdoor Timer HB77R
When switched to "On", the little red LED lights, but there is no power to the accessory outlet. A reset, unplugging the unit and reinstalling the batteries makes no difference.
HB77R is discontinued timer.
If reset and battery change will not restore functionality, then replace timer with HB800RCH lifetime timer, or HB880R outdoor timers:

First off is the black wire feeding the gfci going to the brass colored screw? If so make sure the black wire coming out of the timer is attached to the brass screw on the gfci and the white colored wire is attached to the silver screw. If these are all connected properly it is possible that the fan isn't wired properly.

There are no repair parts for intermatic/malibu power packs.
You can buy cheap plug-in timer, and plug power pack into cheap timer.

The clock motor gets weak and sticks on the tripper and then stops working.
Possible solution: Some people report they disassembled clock motor, cleaned the gears and added a bit of vaseline or white grease to gears because they get dirty.
Then afterward, you might try duct tape to seal unit from dust
Others report they got the clock motor apart and didn't mark parts and take photos along the way, and forgot how tiny gears went back.
My experience with clock motors, and motors in general, is when they slow down, they overheat and don't last much longer.
There are no replacement clock motors for ML series power packs, which is shortcoming since Intermatic makes replacement clock motors and modules for many of their products.
Work-around: Set timer to override, then plug power pack into cheap wall timer.
