I keep the cover clear of snow/ice. It's one of those space-saver lifters, has the arm within a sleeve. It'd given me resistance several times before, but always dropped down. This time I was rocking the darn thing to get it to give, and give it did! When I called about service, the girl told me I could still use the tub. Ummm.. yeah, half of it, lmao. Tech's coming out tomorrow (thank you, God) to replace it and put in the new hand jets. And yes, Jim - this is number 3. Hope I'm done for awhile.
