    The heater is not working. This unit has a heater. When switched on it blows warm air downward into the room. This heater is no longer operating.

What is not working ---- Heater or Fan??

    1. So, if heater is not working and the fan is working (you may check its working by the humming sound and feeling the air), then there are two possibilities:
      1. Check the heater element/coil for its continuity. It may be blown. If not then,
      2. Check supply available at terminals of heater coil by switching on the heater. It must be equal to the supply voltage. You may connect a bulb (say 100 W) at terminals of the heater to see weather supply is available or not. It must glow with it full capacity (mean not dim).
    2. If the heater is not working and the fan as well, then check the connecting cord. It may have been broken and the supply might not be reaching. For checking it, switch on the heater by putting any button at it. Ensure that the supply plug should be out. There may be three pins at the plug. One, the bigger one for earthing. And the two remaining will be of phase and neutral. So now you give supply to one of the terminal (may be phase and neutral) by taking a piece of a wire ( take safety) and check that the same is coming at other end or not.

Trouble shooting

for trouble shooting an air conditioner or heater its always important to ask your self one question before getting your hands in their-What is it doing and what is it not doing.This is the fundamental question to ask yourself no matter what machine your working on(washer dryer,dishwasher,microwave etc).If your unit is blowing air but not cooling 90% of the time your problem is in the condensor section of the unit.

Trouble shoot heater fan on a 1996 Plymouth Voyager Van

Check for 12 volt power to resistor under dash on passenger side. Follow wires from under glove box (from blower motor) to resistor, which will be where wires are connected on duct work. You should be able to test for 12 volt DC power there.

Can't light pilot light on hot water service. Gas to property is connected as the gas stove works.

There should be a trouble shoot guide on the hot water tank. I have had to do this many times. You just need to read the trouble shooting guide & be very careful. I hope this works for you.
