    No Hot Water
    I have a Rheem Power Vent water heater, Model 21VP40E-1A. The fan is continues to run. The ignitor does not come on. No glowing or clicking. Do you know what the problem might be?

    Could be a defective ignitor. Remove and look to see if it is cracked or use a ohm meter to test.

    You also need to check your vacuum switch. Do this only if you are qualified.

    Your igniter won't light if your vacuum switch is not working.

    You can short the wires on your vacuum switch. All you need is a wire jumper or paper clip for this test. Turn the power off. Remove the leads to the vacuum switch and short the leads. Turn the power back on. If the gas works then, you may have a faulty switch or a plugged vacuum line or water in your line. If a plugged line, you can actually buy new line and run from the motor to your switch on the outside of the tank. Rheem recommends this.
