I'm having an issue with my PG2000. Pool installed 6 years ago and this thing was erratic last season. On 3rd bulb. Unit would not fire last season - no fan, no light. Fuses were good, bulb brand new and unit had power. I was thinking it was the fan, and we replaced that. Unit fired right up and ran, but would never re-fire. Not a day later, or the rest of the season. The installer I used was a jerk (after he had my money) and I really don't want to call this guy.
