SOURCE: Unable To Keep Pilot Light Lit!

I have a Williams top vent gravity wall furnace (model 5009622) and I had the same problem. I had to take the cover off the furnace -- screw on top and two at the bottom (open the access door and there is one screw on each side) to get to the reset button for the vent safety shutoff system. On my furnace it's on the left side toward the top of the unit. I pressed the little red reset button and it's been working ever since. If your furnace is properly installed and doesn't have bird's nest in the chimney, it should work fine. Good luck!

do you have the sensors at the bottom of the door? if so they might be out of alignment. all you have to do line them up by getting the green light solid. let me know if this helps you.

SOURCE: pilot will not stay lit after button release

most likely you have a thermopile that has low output. it takes about 100mv to maintain pilot light

SOURCE: Lift-Master garage door opener stopped working

The motor will probably need rewinding.
Professional job. Don't forget to take the condensor with the motor.
Or alternatively, if money isn't a problem,, get somebody out to look at it.
There ya go:)

Riso EZ 200E model gives error message A-01 -211

A-01-211 basically means there is master material under the position sensor while in standby. Referring to the manual open the master drawer and clamp rewind the master material back on it roll and close the lid/clamp. This allows the master unit to reset or to say "return home" action. Now open and re-insert the master material in its proper place. This is similar to A-34-218 code.

Riso RZ 220 UI The master drum will not come out and the green light is not on.

This is for master drawer not responding to green light to be released question. Try turning ON machine (turn off first) while holding down the reset button. Also a mechanical way is a small hole to insert a pencil, eraser end first, just below green latch area. Just insert hold in while squeezing release latch. to drawer.

Riso rz 220 the code A17 209 continues to come up


Yor cutter unit is not in the home position.
Open the front door, take out the master unit, remove the master material, lift the green handle and look to see if you can see a white plastic knob (that is the cutter) make sure it is to the front of the machine, if its to the back of the machine very carefully move it forward until it wont move anymore.
If it is in the front of the machine then the microswitch is probabally faulty and will have to replace the cutter unit.
