If the back plastic piece is cracked it is no good,replace it with a new one.should also change the filter at the same time....inside the plastic piece there is a steel ball and a spring....also good idea to replace them also..if this unit has a glow bar you ill need to adjust the air pressure to the correct setting.if it has a spark plug the adjuster goes in jst past flush....there is a slight bevel in side that you should be able to see.

Hi, I do not no the age of this unit, but when a furnace is installed, it is set up for Nat. gas., and they most always leave you a small package taped to or near the gas valve that has the spring and L.P. orfice in it, in case it is needed. See if you can find it first. If not, get all of the numbers from the main gas valve (mgv) and from the unit heating plate attached, b.t.u.If you can't find it, at the top of the main valve, you will see a brass colored screw slot.May be aluminum. Turn off gas and power. Remove the threaded screw cap and remove all small parts, a spring, a plastic or maybe aluminum round orfice, about 3 pieces. Keep them in the order you remove them.Replace with the L P Parts if you have them. If not, you will need to take the parts and all numbers you can get from valve and unit to a appliance parts store to purchase.You shouldn't have to adjust the gas pressure as now days they are the same for nat. and L P.About 3.4" of water colume. Thats a different name for pressure. Very easy for you to do. Good Luck, Shastalaker7

Bmw e46 heater blower not working

Time to get the blower resistor replaced. Simply carry out the following steps. Open the Glove box. Remove the three phillips screws across the top of the open box. Remove the two phillip screws that are deeper in on the sides of the open box(nine and three o'clock). Hard to see, use your flashlight. With these five screw removed remove the glove box. Disconnect the flashlight charger plug, and the glove box light connector. Pay attention to the wire routing. Remove plastic cover behind glove box. Locate motor and metal link to one of the a/c doors. Remove the metal arm from the plastic clip. Slide motor out and disconnect. There is an odd shaped black plastic piece with two T-20 or 25 Torx screws that need to be removed. Remove plastic piece. The Final stage is located behind the metal arm for the a/c door. I remove the floor heater duct for more room. You may or may not feel the need. If you wish pull on the leather extension to the center console outward until you hear a loud plastic cracking. Stop. Take a deep breath and know that you have broken nothing important Remove heater duct careful not to break the blend air door cam (white) and the lever connected to it (black). You can pull that black lever out if you are patient. Back to the final stage now that you have more room. It is the component with the 5 0r 6 large gauge wires on the connector. Push back the black plastic clamp while pulling/wiggling on the connector. The final stage should come out, then disconnect the connector. Reinstall all. Make sure the heater duct is installed properly if you removed it.
