About the Marley 4520-0011-001
This is a genuine Marley Engineered Products high limit, part 4520-0011-001, used in Marley, Qmark and Berko electric heaters. It is a linear-style limit control built around a Therm-O-Disc 10H11 bimetal thermostat and carries a 325°F rating.
The limit opens the heating circuit when temperatures inside the heater go above its rating, then resets on its own once the unit cools. It is a single replacement control.
This part number is close to other limits in the same family (4520-0011-000 and 4520-0011-002), so match the number on your old part and check your heater model against the compatible-models list on this page.
Installation Tips
Turn off power to the heater at the breaker or disconnect before opening the unit, and let it cool fully before handling the limit.
