Thermostat (Mgt)

What's included: One thermostat. Install notes:
  • Disconnect power to the appliance before attempting removal or installation to avoid shock or ignition hazards.
  • Handle the sensing element and terminals carefully to avoid damage; ensure secure electrical connections and proper routing of any capillary or sensor lead.
