Switch on the water heater for two hours, then run the hot water faucet to see if the water is well heated. Check the breakers and fuses related to the water heater in your distribution panel.

Move your gas line back in and tighten it well.

How to test water heater element in rv. Each element will have two electrical wires running to screws keeping the element in place. Most of them plug into a 110v outlet right in back of the heater. First, make sure the heating element is off.

Check the ac power to the element, if there is no power, replace the relay. Reconnect the circuit to its power source by activating the circuit breaker. You can find it on the side of the element.

Unscrew and remove the heating element from your water heater. Replace the chamber panel and insulation of the thermostat. 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.

These components prevent overheating by breaking the electrical circuit. How to troubleshoot a defective thermostat on. Screw in your replacement heating element at this point.

Your old heating element will probably show visible corrosion. Water heater element testing should only be done when the power is off. The water heater tank must have factory equipped heat exchange tubes welded on it already.

You may insert the power pluck and hold a tester at the heater’s connecting point to check if the power is available. Use your screwdriver to loosen the screws just a bit and then remove the wires from the screws safely. 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).

Check your heater’s power connecting point. If there is power to the element but no heat, replace the element. You can test the element with the ohms function or a continuity setting.

• skin mounting allows the water heater to be hooked up with plumbing and electrical before If the connection point does not get electricity, then. Water will likely begin pouring out when you remove it—don’t worry about this.

Test the upper water heater thermostat 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. 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.

One probe touches one terminal, the other probe touches the other terminal. Remove this safety cover to start testing your water heater thermostat. You can use a vom to measure the resistance.

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. To use the multimeter and test your water heater element, you will need to set the multimeter to the lowest setting for ohms resistance. The lowest setting can vary depending on your model.

Remove the square black cover to expose the rv water heater thermostat switches. Odds are the switch on the heater was left always on and electric mode was controlled from an inside switch. Confirm dc power is present through the yellow wire from the board.

Once done loosening the screw, make a note of the wattage value of the heating element. Safely remove this insulation first gently so that any wire doesn’t accidentally get pulled off. It is very important to make sure the power is off.

Any reading there will indicate a short in the element. You can then test the element with the ohm scale or continunity setting. Shut off the breaker and tag it so that no one turns it back on.

A new water heater tank with this feature must be installed to use the heat exchanger. Use a vom, dmm, or ohmmeter or multimeter set to read resistance or ohms as follows: Also measure the resistance between each of the two probes and the case or base of the element.

Testing the element shutting down the water heater. We will need this wattage value to test the heating element of the water heater. The first thing you want to do is turn off the power.

Connect one alligator clip or touch one probe of the vom to each terminal on the water heater element. 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. Rv water heater troubleshooting is relatively simple if you understand the basic operation of the unit.

But if there are no readings then the thermostat is faulty. We can round that number up to 14 ohms. • a heat exchange option is available.

They cannot be added later. A dial usually does this on the tool; Confirm ac power is present.

So at first make sure your power cord is okay. 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. Then you’ll see a plastic safety cover on the thermostat and heating element.

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.
