Rain Bird E-9 Controller Dead After Power Outages: Reset and Diagnostic Steps

Newbie user: Rain Bird E-9 controller "dead" after power outages. Only checked power supply so far.

Resources and Checks

Manual: E-Class manual (discontinued but manual available).
Transformer check: 110V at outlet? If yes but no 24V at controller terminals → bad transformer.
Hard reset: Unplug transformer 1 min, replug. Turn dial to Auto, remove lower cover. Momentarily short two contacts in RESET tunnel (right of terminal strip) with small screwdriver. If display returns, reprogram.

Worst Case

"Verify controller still getting power from transformer with multimeter (24-27V at terminals). If power present and display blank, electrical surge exceeding built-in surge protection may have damaged microprocessor. Controller must be replaced."
