If you find that the water heater is not capable of maintain the correct temperature, you need to check the thermostat. I have put one of those mains tester screwdrivers onto the live feed from the switch that goes into one side of the thermostat and it lights up . But if the water is hot that becomes later becomes cold, then you have a damaged lower thermostat. Leave the upper thermostat in the lowest setting and test the lower thermostat. Also check why the overheat thermostat initially tripped before re-connection the power supply. So far so good. To test the element, you need to do two tests - a continuity test between the two terminals will . Drum Immersion Heaters for High Viscosity Solutions and Adjustable Stainless Steel Mounting Bracket TAT30004 TAT30004.

The panels are usually on the left or right side of the water heater unit. The thermostat has a red dial that sets the temperature from about 40C to 70C. This book provides a detailed introduction to the principles of aircraft electrical and electronic systems. When a water heater no longer produces hot water . Remove the panel that corresponds to the thermostat that needs replacing. Buy a clamp meter pal, turn on at programmer if stat is working ok. On the wire coming out of the stat, put the clamp meter on and the imm heater will draw approx 13 amp. Steps to test the heating element: You will be running a continuity test to see if electricity sent into one end of the element comes out properly at the other end. Getting different outcomes means that one of the two is defective. This book is written expressly for non-scientists and is an effective tool for the busy technician or engineer working with thermoelectric thermometry in metallurgical, chemical, petroleum, pharmaceutical, and food processing areas.
