next to the filter is the fan the cover for the fan should come off maybe two screws or lift off now the fan should be in what looks like a upside down snail the fan is in there , Now you can blow the fan out with blow on a vac or at the top of the snail there are some bolts you can undo and slide the fan out watch the elce lead on the fan. you can then clean this with a vac and paint brush. This a general view of how to clean a fan you should be able to work it out from this .

Pressure switch is bocked inside try a small drill bit to clean down the connection tubes and blow it out after , check hoses are not blocked or split ,

Check the valve and jet. The chances are that the jet is clogged. Depending upon where you have stored the unit, the jet may be clogged by a spider that was attracted to the odor of the natural gas.
Should be an easy fix.
Let me know if you have any problems or questions. Thanks.

Hi,
Your problem could be or probably is with the regulator...not enough gaspressure...

Propane, LP, or Natural Gas Regulator Problems
heatman101

The Propane tank is equipped with an OPD (Overfill Protection Device). More often than not it has locked of the grills regulator. (I'm assuming you have already checked and cleaned the burners) To solve the regulator problem do the following:

1. Turn the tank valve OFF.

2. Disconnect the hose from the tank and wait 5 minutes.

3. After 5 minutes, reconnect the hose to the tank.

4. Turn the tank valve ON VERY, VERY SLOWLY (Slow Motion, slow), until the valve is fully open.

5. Light the burner that's farthest from the tank first and turn it to it's highest setting. Does the flame
height look correct? If so, light the remaining burners the same way. Have all flame heights
returned to normal? If so, you solved the problem.

Remember, after turning the tank OFF for any reason, always turn the tank back ON Very, Very Slowly.

If that didn't solve the problem, you need to replace the grill's hose/regulator assembly. You can buy one at any home center or hardware store that sells gas grills and accessories. Take your old one with you for comparison purposes.

I hope all of this helped you troubleshoot and solve the problem. Please let me know and Happy Grilling!

Either the manifold valve for that particular burner has either failed or the burner orifice is clogged. The only way to check it, is to turn OFF and disconnect the gas and remove the the cooking grates, the flame tamer and the burner. Looking inside of the grill, where the burner was removed, you will see the burner orifice, which can be removed with appropriately sized open in wrench. Once it has been removed, look at the small hole in one end, carefully. If it appears to be clogged, either blow through the opposite end or use a straight pin the same size as the hole to clear out the obstruction. Whatever you do, don't make the hole larger! If it was clogged, you just solved the problem. If it wasn't clogged, check the venturi valve/tube on the open end of the burner you removed. It may also be clogged.Simply tapping it lightly with a screw driver handle, will often clear out an obstruction. If not, carefully probe the opening, until it's clear.

If none of the above solved the problem, the Manifold Valve will eed to be cleaned or replaced.

To do this, it will require the removal of all the plastic knobs on the the front of the control panel and then the removal of the control panel itself. By doing that, you should have complete access to the manifold and then can unscrew the couplings and remove it. Personally, if I were doing this, I'd replace the manifold valve, rather than trying to dismantle and clean it. Generally, you can purchase a new one from your grill's manufacturer.

Hope this helped you to troubleshoot and solve the problem.

Are you able to match light the burners? Is there any gas getting to the burners?

Here is a wewb site of what may look lkie below.. You call this a funace listed as a smoker under this question which makes it sort of confusing

check the orifices they can get clog!

try opening the tank really slowly. the tank has an overfill protection devise built inside and if it is opened too quickly it can restrict the gas flow to the burners. hope this helps.
