61. rs on the right side of the oven assembly for electric dryers A sail switch consists of a round damper plate on a lever arm which is in contact with an electric switch When the air blower comes on it draws air through the gas or electric burner This creates a negative pressure inside the burner box and this negative pressure pulls in the round damper and activates the sail switch If there is improper airflow the damper will not pull in preventing the burner from coming on Improper airflow can be caused by improperly designed exhaust ducting where the duct run 1s too long or has too many sharp bends in it It can also be caused by a lack of make up air K HI LIMIT Gas and Electric Models Only A hi limit thermostat is located at the burner This is an manual reset disc type thermostat set at 330 F 166 C for gas dryers and at 290 F 143 C for electric dryers If the flame in the burner should get too hot this thermostat will shut off the burner This is generally caused by low airflow through the dryer L MANUAL RESET THERMOSTAT This is located inside the dryer in the lint compartment above the lint screen This thermostat senses the heated air after it passes through the tumbler basket If the air temperature gets too hot the thermostat will shut off the burner The dryer will not run until the air temperature cools down At this time the manual reset thermostat must be reset manually or the 24 VAC burner circuit
