How To Test Water Heater Element In Rv. A bad element is possible, but actually not all that frequent a failure unless the rv was exposed to hard water much of its life. A dial usually does this on the tool;
A new water heater tank with this feature must be installed to use the heat exchanger. Again, the water heater is working, but it’s mixing with cold water at the outdoor faucet, so you can’t get hot water to the rest of the rv.

Also measure the resistance between each of the two probes and the case or base of the element. Any reading there will indicate a short in the element.
How To Test Water Heater Element In Rv
Confirm ac power is present.Confirm dc power is present through the yellow wire from the board.Connect one alligator clip or touch one probe of the vom to each terminal on the water heater element.Each element will have two electrical wires running to screws keeping the element in place.
First, make sure the heating element is off.How to troubleshoot a defective thermostat on.If the connection point does not get electricity, then.If there is power to the element but no heat, replace the element.
In order to find the resistance of the heater element from the above described section, we must algebraically modify the formula to read (r = v/a).It is very important to make sure the power is off.Most of them plug into a 110v outlet right in back of the heater.Move your gas line back in and tighten it well.
Now to check the lower thermostat, you need to set the dial of the upper thermostat to the minimum and set the lower thermostat to the highest.Odds are the switch on the heater was left always on and electric mode was controlled from an inside switch.Once done loosening the screw, make a note of the wattage value of the heating element.One probe touches one terminal, the other probe touches the other terminal.
Reconnect the circuit to its power source by activating the circuit breaker.Remove the square black cover to expose the rv water heater thermostat switches.Remove this safety cover to start testing your water heater thermostat.Replace the chamber panel and insulation of the thermostat.
Rv water heater troubleshooting is relatively simple if you understand the basic operation of the unit.Safely remove this insulation first gently so that any wire doesn’t accidentally get pulled off.Screw in your replacement heating element at this point.Shut off the breaker and tag it so that no one turns it back on.
Since we know that the hot water electrical circuit feeds 220 vac to the 16 ampere heating element the resistance of that element is equal to 13.75 ohms.So at first make sure your power cord is okay.Switch on the water heater for two hours, then run the hot water faucet to see if the water is well heated.Test for proper voltage on each side of the water heater element by touching one probe of your multimeter to each screw, while touching the other to common ground.
Test the upper water heater thermostatTesting the element shutting down the water heater.The first thing you want to do is turn off the power.The lowest setting can vary depending on your model.

To use the multimeter and test your water heater element, you will need to set the multimeter to the lowest setting for ohms resistance.Unscrew and remove the heating element from your water heater.Use a vom, dmm, or ohmmeter or multimeter set to read resistance or ohms as follows:Use your screwdriver to loosen the screws just a bit and then remove the wires from the screws safely.
Water heater element testing should only be done when the power is off.Water will likely begin pouring out when you remove it—don’t worry about this.We can round that number up to 14 ohms.We had this happen to us (very early on in our rving life), and it had us running around all over the rv trying to troubleshoot everything else we could think of.
We will need this wattage value to test the heating element of the water heater.While a book would be required to cover everything that can go wrong with an rv water heater, this entry will serve as a brief overview of water heater operation and the.You can find it on the side of the element.You can test the element with the ohms function or a continuity setting.
You can then test the element with the ohm scale or continunity setting.You can use a vom to measure the resistance.You may insert the power pluck and hold a tester at the heater’s connecting point to check if the power is available.Your old heating element will probably show visible corrosion.
• a heat exchange option is available.• skin mounting allows the water heater to be hooked up with plumbing and electrical before
