I have an Atwood unit with auto ignite that will only start if the cover door is open which suggests it has something to do with air. I have replaced the ignition unit and the regulator and it works perfectly when the door is open (continues to work when door is closed but seldom will start again when the water cools off). The igniter fires (clicking) but will not ignite. Any suggestions where an adjustment should be applied?

Although this is not a thread you started the OP hasn't responded so might as well try to answer your post.
First off....
Post year & model of your Atwood WH.
What does flame look like.....Blue and Strong slight roar
OR Yellow and kinda quiet?
Have you do ANY cleaning....remove burner tube (clean with small bottle brush) and make sure burner spreader plate at end of tube is parallel with end of tube, remove gas orifice (screws into outlet of gas valve) soak in alcohol and then blow thru it (NO HIGH PRESSURE), run wire thru combustion/exhaust chamber....out exhaust/tie rag to wire then pull back thru to 'sweep' 'U' tube, wipe spark electrode/igniter with emery cloth to remove any soot/carbon.
Make sure spark electrode wire terminal to transformer is clean/tight
Reassemble ...
Gas orifice, burner tube, spark electrode...making sure mounting screw is clean/tight (ground source)
Adjust air shutter (slotted tube on burner tube) is OPEN 1/4 then fire off propane flame and fine adjust air shutter so flame is BLUE/Slight ROAR
