[T3] Took apart my electric AAR . Mine would not fully close . It takes some time yet it's not that bad . The heater was fine yet needed to remove the heater housing from the valve since it's the only way to remove the valve through the top by removing the oil bath pipe . I saw mostly what causes the valve to bind is fine surface rust in the valve bore , once that happens you get slight scoring on the valve which is stainless and the bore which is steel , i think this allows the oil to build up on the valve , if the bore and valve had no scoring the oil would not build up. I polished the valve and bore cleaned it well added a small amount of SAE40 to the valve hoping to keep rust from forming , I though anti seize may have been better then adjusted the thermal spring to close a bit sooner put the valve back together and now it works I cut slots through the crimped area and it was easy to bend them up to remove the valve assembly from the heater can and once repaired bent them back over .
