Expert:  Bryan replied 7 months ago.
I'm sorry but your reply didn't come through.
Customer: replied 7 months ago.


Yes I have replaced thoses parts 2 valves and the 2 temperature sensors

Expert:  Bryan replied 7 months ago.
okay, this is a tough one. so we are down to a few parts really. one would be the radiant sensor on the side of the heater can.. the electronic control. or the timer. Now in rare cases the centrifugal switch on the motor could be bad also. does this happen in both timed and auto cycles?
Customer: replied 7 months ago.

The radiant sensor works fine. it glows red the light of which is received


by the infrared sensor and the gas valves open and flame up well. However the main flame is only on for about 7 secs the then is extinguished with the opening of the high temp sensor , and the process


continues. Is the hi temp sensor suppose to control this or is it a safey in case of too much heat?

Expert:  Bryan replied 7 months ago.
okay well the temp is controlled by the cycling thermostat.

which is on the blower assembly and I believe you replaced. if that fails to shut the heat off then the high limit will. have you tried running this without the vent attached ? completely removed from the dryer and if so does it do the same thing ?

Expert:  Bryan replied 7 months ago.
