My Neptune dryer starts to heat then shuts off after 15 to 30 seconds. same results with exhaust duct disconnected. Cleaned internal blower and associated ducts. Then, I inserted a thin sheet of metal between the hi limit thermostat and the flame to trick the sensor but same results. I am thinking about buying the coil kit gas valves Part Number: AP3094251. Is this the right part number and part to change out as a first test.
Is the air flow supposed to be steady or periodicaly pulsing like a quick loss of flow (surge). Mine has a tendency to do that with and without the duct. I cleaned the blower and all the ducts inside the dryer.
Thanks in advance.
