Suburban Water Heater Problem

On our suburban water heater the switch went bad right at the water heater. The next thing to check is the heating element itself. If it shows low ohms it is good. If it shows an open it is burned out! Make sure your Volt Ohm Meter shows 0 ohms when you short out the two test leads. In addition to our bad switch I accudently burned out the heating element. Kind of glad I did because the element was badly corroded from the extremely hard water in AZ. Now it heats much better with a new element. If If your problem is not the switch or the element then the thermostat reset may be an issue. Just follow the source of the 110 V to the thermostat. Check that it gets through and then verify it is getting to the heating element. Pretty easy to trouble shoot with a VOM.
