  • Opens the heating circuit if temperatures exceed safe limits to prevent overheating.
  • Helps protect the heating element, housing, and internal components from heat damage.
  • A failed thermostat can cause no heat or intermittent heating in the dryer.
  • Works with the dryer's safety controls to maintain normal operating temperature.
What's included: One high limit thermostat. Install notes:
  • Disconnect power (and gas if applicable) before servicing; allow unit to cool completely.
  • Located on or near the heater box or blower housing; follow your model's service manual for access.
  • Replace with the exact part number to maintain original safety settings.

Questions & Answers

For Whirlpool High Limit Thermostat (Limit Cut-Off) (Part Number: OEM18028929)

Attila for Model Number DLG2302W

Hi me again. Question I am confused there is a thermostat next to the thermistor in this model .Its right where the exaust is going outside. its not on the back like on the other models.It looks like the Sub LA -1053 . I ordered the kit and inside was the thermostat 53-1096 high limit thermostat.Are this 2 are same or different? I am trying to figure out I know you suggested the Gas valve . And again my question is that thermostat controls the temperature when the Valve should come on when the temperature drops. and there are 2 more thermostats one under the flame sensor and the another across the flame sensor what are there functions? thanks

Attila, The thermostat next to the thermistor on the unit would be a thermal fuse and if it fails then it will cause the unit to not operate. What causes the gas valve to cycle on and off would be the cycling thermostat, or in this case that exhaust thermistor. If the gas valve is shutting off to rapidly, check the venting of the unit and if it checks ok then the gas valve would be the most likely issue.

Ray, The flame sensor would have a "closed" circuit when tested "cold" (room temperature) with a multi meter and the wires disconnected from the terminals. At present, it sounds more like an air flow issue, you should disconnect the exhaust vent from the back of the dryer and check and clear any kinks, or clogs and debris from the inside of the pipes/tubes and vent hood. You also want to remove the lint trap and remove any lint or debris that has accumulated in the duct assembly, under the filter.

Hello RJ. Based on the information you provided, the thermal kit LA-1053 is bad and will need to be replaced in the unit.

Hello Grace. Check and make sure you have 240 volts coming to the dryer. Check and make sure the unit is not set to Air Fluff. If so, unplug the wires going to the element and trace for the lose of the voltage. When you find where you lost it, that part will need to be replaced. You can test these with a multi-meter MA-DM1. They should read closed for continuity. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
