I'll dig around, but one thing to check first. Is your thermostat configured for it, and is your control box in the AC configured for it? We have the heat strips in both of our AC's, and there is a setting listed on the t-stat for it. Fan, AC, Furnace, Heat Strip I believe is the order on both t-stats. On the front one, same list, but the Furnace or Heat Strip setting runs the heat strip.

At least in Heaven, RVs will be perfect, and I won't have to keep fixing them.
