i have just replaced the thermostat but i still have a continuous alarm going off. Is there something that could be causing an over heat.I ran it yesterday for a few hours with the alarm going off constantly(very annoying). The motor ran fine. When i take the cover off it is hot to the touch but isnt every motor?i imagine the thermostat opens at 185 but i am not sure.Any help would be greatly appreciated

Thanks

Jeff

First I would disconnect the temp sensor and if the alarm is still on that means the warning amplifier is bad. If the alarm goes off then you need to get a reading on the actual temp of the head. If it is below 190 then the sensor is bad.
