[QUOTE="Phil.cc, post: 503379, member: 30161"] I have two convector room heaters in the pool enclosure, one at each end, they have been working perfectly for about twenty years, but one of them now cuts out after about ten minutes, then comes back on about twenty minutes later. The heaters are about five feet long, with two long vents at the front, one at the top and one at the bottom. Behind the bottom one is a rotary cylinder fan unit and motor, there are three cylinder fans that rotate freely via a steel rod, two on the left then the motor and one on the right, air is sucked in from the lower vent, it goes through a car type radiator above and warm air expelled through the top vent. To me, it sounded like a faulty thermostat, (this is adjustable), it's not needed so I bypassed it completely, which means, the same power supply to the two heaters via two switches, that didn't work as it still cuts out. The motor gets hot, I changed the capacitor, no difference, I have a spare, brand new un-used heater unit, I swapped it, and there's no difference. The vents have foam filters, to stop dust etc, if these were restricting the airflow, then that might cause the motor stopping...so I removed the foam, the motor still cuts out after about ten minutes and comes back on after about twenty minutes, the other heater works fine. Any ideas please? [/QUOTE]
