I have a Model C152E Aerus Ultralux canister vac. It developed a frustrating habit of refusing to run unless the bag door was opened and forcibly closed, (following which it ran perfectly and consistently). (Gentle closing did not fix it). I surmised that the problem was the little switch on the door, and took the vac off to a service man, who agreed, did something, (for $88) and returned the vac to me, fixed. The original problem was indeed fixed. But it now, (immediately after its return from the repair), has a new problem - it runs for 3 or 4 minutes, then shuts off. This happens completely spontaneously, even if the vac is left completely undisturbed, (ie no relationship to movement or use). After 60 seconds, (again not touching it), it comes back to life, runs for a minute or so, and then stops again. I reckon that it is overheating and the thermostatic protection is active. The service depot says that 1) this indicates that the motor is failing 2) It needs a new motor, but 3) the motor for this model is no longer available, so 4) we will need to buy a new one, (which they will happily sell us). Is this plausible? Do motors overheat as they age? (The motor is not making any noises suggesting worn bearings or anything.) The service man had volunteered that he had checked the brushes, and they were "in excellent condition". The bag, prefilter and post filter are all new, and the suction full, (no apparent obstruction to air flow). Since the service man had the machine apart, might the thermostat have been disrupted/ (ie. the motor is not the actual culprit, but just the thermostat.) Is this all bad luck and old age, or is my current problem the result of inadvertent (or, worse, deliberate) disruption of internal operations in the machine? (The development of the problem immediately after it was serviced certainly suggests a relationship between service and problem, but things do happen randomly, and the association may, (as the service man claims) be due to chance.)
