DESCRIPTION
Simple and Easy to Operate.

The Magna-Clave features a series of safety measures, like a Pelton & Crane-patented door lock that seals the entirety of the sterilizer’s rim, as well as clarity features like a series of indicator lights (“Power On,” “Heat On,” “Sterile,” and “Open Door”). Due to its large capacity, ease of use, and quick cycle speed (completes a flash cycle in 18 minutes from a warm start), it should come as no surprise that Pelton & Crane’s Magna-Clave is an industry-leading sterilizing unit

Clock Stops when heat on light is on

it starts fine, warms up fine, reaches good temp and timer starts, but when it does a cycle to warm up again and the heat on light turns on the timer stops and doesnt continue until the heat on light turns off

is this a latching relay fault or a clock fault? it didnt had a latching relay when they purchased it for some reason and it worked fine before

The clock is functioning during warm-up.
The clock keeps ticking even while it's warming up.

Voltage diagram? Voltage Leak
I am having an issue with the door solenoid burning out. I replaced one and it was good for a few months then burnt out. Replaced another and it burnt out in a week along with some switches. I replaced all the switches, main relay and electrical contractor along with another door solenoid and it burnt out again and the door open light was slightly on even when the unit was in power off mode (but would light with full intensity when power was applied which made me think leak somewhere). I replaced the wall thermostat on the suggestion of a fellow tech and that fixed the weak light on the open door but I don't want to burn up another solenoid. SO before I throw another solenoid in this beast does anyone know what the voltage SHOULD be on the #2 wire in the different positions? # 2 wire that connects to the door solenoid has a leg coming from the pressure interlock switch and the open door light. RPI told me that the solenoid shouldn't be under constant voltage but I have 120VAC coming from that #2 wire to the body of the unit but I don't know if that's an acceptable test point. I don't have any voltage going from where the #2 wire connects to the solenoid to the pressure interlock switch. Reply
