Well....my teledyne series 2 will fire up and burn well for about 3-6 minutes. After that, it sounds like something is reseting and it starts to flutter/click fast. I basically have to turn the heater off and then turn it back on. It only takes another couple minutes for the issue to start all over again. I went up and found that the gas valve is making all the noise and it is a $300 part. Could I take apart the gas valve and repair it?
