the high limit will cause an EE12. The high limit switch is a normally closed bimetal switch. Electric current flows through it and allows the main circuit board to provide power to the fuel pump. If the high limit switch is open, no power flows through it and the circuit board cannot operate the fuel pump. The. Hi Brian! Thanks so much for your kind words. Since your high-pressure switch is open then this could be caused by a bad high-pressure switch, an outdoor fan that does not work, a dirty condensing unit, or a restriction in your refrigerant system. If you have a bad restriction in your system then the pressures might not equalize.

Thus the NC relay contacts are closed when the NC limit switch opens, as you want. The original 'high limit switch' (located down low on burner stack) was set to trip open and send alarm at approx 300*F. The recall box uses a different high temp limit switch installed higher up on burner tube and set to trip open at approx. 700*F. When the new recall high limit switch opens it trips all power to fridge. The limit switch includes a sensor in the heat exchanger to determine when the air is warm enough to circulate. Once the air reaches a preset temperature, the limit switch turns on the blower. The switch also turns off the blower ff when the air temperature falls below a lower limit. $32.97 Description This High Limit Thermostat Only Fits The Newer Style Midmark M11 Autoclaves With The Green LCD Screen Part #MIT093-4040 Midmark Part #015-1637-00 HIGH LIMIT THERMOSTAT Automatic reset Opens at 450°F ± 25°F Closes at 364°F ± 20°F 15A @ 120VAC; 10A @ 250VAC 1/4" Quick Connect Tabs See below for Serial #'s this part fits.
