Furnace needs vaccuming.

    Instructions.Things You'll Need:
    Vacuum cleaner with hose attachment
    Screwdriver
    Scrub brush
    Old toothbrush
    Cotton swabs
    Toothpicks

    1. Cut the power to your furnace by shutting off the breaker switch. Remove the front safety panel from your furnace. In gas and oil furnaces, the pilot light and fuel supply should be shut off for safety.

    2. Vacuum the interior area. Use caution, do not displace any wiring. Use an old toothbrush to carefully remove grime and dust build-up, then vacuum the area a second time.

    3. Clean the furnace's blower assembly thoroughly, using a toothbrush, toothpicks and cotton swabs. Remove build-up from all surfaces of the assembly, paying special attention to the blower fins. In some furnaces, a blower cover must be removed to access the fan assembly. Vacuum up displaced debris.

    4. Use a large, dry scrub brush to clean all vents. Pull off the furnace filters and replace if needed. Disposable filters should be replaced yearly. Vacuum permanent filters well, then use the scrub brush to remove build-up. Vacuum a second time, or blow dust out with an air compressor.

    5. Put the furnace back together. Replace filters, and any safety covers (except the front panel) you have removed. Look for loose connections and signs of corrosion. Check for worn or melted wiring. If everything is in order, re-connect the furnace and turn it on.

    6. Allow the furnace to run for several minutes to check for unusual sounds or smells. Disturbed dust commonly makes a crackling noise, which should cease after a few minutes. If you smell burning gas, oil or electrical wiring, shut down the furnace immediately and call in a professional.

    7. Replace the front panel when you feel everything is running smoothly and safely.

Sounds like you have a leaking head gasket maybe. Does the smoke have a sweet smell to it? If not it is oil or fuel.

I have a 5L-E toyota hilux that runs fine at idle yhen when you rev it to about 2000 rpm it starts to blow alot of white smoke. I have cut injectors out while the smoke is blowing with no noticable...


i believe the engine is running too lean as if it was running too rich it would blow black smoke If it was blue smoke it is oil related eg valve stem seals,valve guides and or piston rings all of these things will create blue smoke if one of the above is worn out

Engines idle goes up and down after warming up and blows blue smoke


If the engine idles for a while then blows blue smoke this is an indication of oil passing the valve stem seals and being burnt in the combustion process. ( When you are at lights and they change and you accelerate away leacing a cloud of blue smoke this is worn valve guides and failed valve stem seals) As for the idle it could be the oxygen sensor is coated with oil and soot and is malfunctioning henace the cpu cannot regulate the fuel setting correctly. Have the valve seals replaced and clean the Oxygen sensor and check for other fault codes

Furnace not cycling properly.


you might want to check the filter, if the filter is restricting the airflow the furnace will over heat and it will shut down. if you turn it off and on it will reset it and it will try again. Pull the filter out half way and try that, if it runs fine then clean the filter or get a less restrictive one.

THE HEATER STARTS THEB BLOWS ALOT OF SMOKE


There are any number possibilities for intermittent running.
1. Bad ground connection at the Ignition Device (transformer, spark box)
2. restricted fuel filter causing fuel starvation
3. crack in the plastic end cover
4. crack in the airline
5. crack in the fuel line
6. crack in the nozzle adapter
7. water in the fuel
8. Others I’m sure I left out
