Gas dryer seems to do everything right but is not heating the cloths. The ignighter comes on at first but no flame ever lights up. I took the front panel off and check the ressistance of the coils and they seemed on target (2-terminal one was ~1200 and 3-terminal one was ~1300 and 560). After putting it together and testing it actually did work once (flame lit up). However its not doing it anymore.
Should I go first with replacing those coils?
