The pool timer is what keeps your pump switching on and running during set times of the day. When the valley sun pounds down and temperatures soar, you need your pump running correctly to help protect your pool from algae buildup.
If the wheel stops turning but the pump functions properly with the manual switch, it may only need a new motor, or possibly require more power (often, pool owners hook up a 220v pump timer to a 110v power source). However, it may simply be time to replace the timer.
The techs at Deckhand Pool Care have the training to inspect your pool timer, ascertain the problem, and either repair or replace the timer. In both instances, the tech then performs necessary adjustments to the timer wheel and to the on/off pins to ensure proper functioning.
