How to Repair a Faulty Kerosene Heater

A kerosene heater may not work properly due to several reasons. Here are some frequently observed problems, along with their solutions.

1. Bad Odor

This indicates that the fuel you are using is of bad quality. This low-quality fuel contains sulfur in greater proportions and it lacks refinement, which results in incomplete burning. This incompletely-burnt fuel deposits on the wick in the form of hydrocarbons, emits a strong kerosene odor, and causes indoor air pollution.
Always use good-quality fuel (K-1 kerosene), which will not cause an odor. Keep the heater in a ventilated room and adjust its position in such a way that the bottom of the burner unit will be settled on the floor appropriately. Do the wick adjustments carefully.

2. No ignition, or ignites to go out in a few minutes

This is a very common situation, often faced by many people. It indicates that either you are running out of fuel, or that there is water content in your fuel tank. You can either refill or replace the fuel, depending upon the requirement.

3. Working very slowly

This indicates that you need to clean the wick. It even occurs when the wick gets older. In such a situation, you will have to replace the wick.

4. No ignition at all

Your heater ignition may work properly, after wick cleaning. In many cases, problems in the ignition occurs due to a faulty igniter. Here, replacing the igniter will solve the problem. In the same way, if dead batteries is the problem, you can replace them. Always use non-alkaline batteries as they reduce the risk of blustering of the igniter filament.

5. Production of smoke

Sooty, black smoke from the forced air kerosene heater can be a result of low-grade kerosene. If your air or fuel mix switch is turned off, it can also produce such smoke. Do not use any flammable fuels like gasoline in the heater.

6. Cannot be turned off

A hardened wick creates difficulties in the shutting-off process of the heater. The wick hardens because of the carbons and other tar depositions on top of the wick. Low-quality or water-contaminated fuel, often cause this problem. It can be solved by removing the depositions and using a good quality K-1 kerosene.

7. Produces high flames

Whenever the heater produces high flames, take a look at the wick first and also check if the heater is properly set on the surface. A wick which is set on high causes high flames. Unpinning or lowering the wick, it will solve your problem.
The repair of this device should be done very carefully. Consult the manufacturer, if necessary. The problem can be easily solved, if you diagnose it correctly. It will save your time as well as efforts.
