About the Marley 4520-0011-002
Part 4520-0011-002 is a genuine Marley Engineered Products high limit for Marley, Qmark and Berko electric unit heaters. It is a linear limit control that uses a Therm-O-Disc 10H11 bimetal thermostat and is rated at 325°F.
When the heater runs too hot, the limit opens the heating circuit and then closes it again automatically after the unit cools. It is UL listed, surface mounted and sold individually.
Related limits 4520-0011-000 and 4520-0011-001 look similar but are separate part numbers, so match the number on your old control and confirm your heater model in the compatible-models list on this page.
Installation Tips
Turn off power at the breaker or disconnect and allow the heater to cool before replacing the limit.
