my dryer runs but the flame only ignites for about 15 seconds. once temp cools off for a few minutes the flame re lites. There was a substantial block in the vent. I've replaced the coils tore apart the machine and cleaned all lint from the lint duct, blower and vent duct. no kinks in the vent duct. the thermal fuse is blown so I bypassed it temporarily to see if it helped. no luck. I assume the thermal fuse blew do to a blocked duct previously. Should I replace the hi limit switch, cycling switch or maybe both?
ANSWER Hello Raymond. It sounds like the gas valve assembly is bad and will need to be replaced on the unit.
