Hi! My Pentair EasyTouch remote controller won't power on. I have changed the batteries several times to no avail. However, it never showed the low battery status, just stopped turning on, no matter how long I hold the button. I can still control the pool equipment from the outside control/maintenance panel. The remote (and all equipment) is about 4.5 years old (first use, Feb 2015). We had this problem with the remote about 6 months ago, and my dad shook/blew/??? and it started working again (he didn't believe me that it was ever broke, just said I must have been pushing the button wrong, ha!). Any suggestions??? Just looked and a new controller runs about $550-575. Ouch!
