•If all the above fails to work then remove the two wires while blowing into the air tube. Blowing into the switch is the same as having air pressure in the plenum. You should have an open circuit until you blow into the switch, then it should close. If the switch does not close try adjusting it, or replace it with a known good one.
Hints
1.Dryer must be full of grain.
2.Light in the fan switch can be used exactly like a voltmeter to test.
3.Make adjustments of the pressure in one quarter turns.
4.Make sure the air tube in the plenum is not plugged after sitting over the summer.
5.Check the bulb in the fan light. It is a 12 volt bulb.
Vapor High Temperature
Symptoms: Dryer runs for only a short period of time, then a shutdown occurs.erature Operation
•This message indicates that the vaporizer on an LP Dryer is not properly adjusted. LP (liquified petroleum) must be vaporized before the burner can operate properly. If LP is being fed to the dryer it must run through a vaporizer before it can be burned. If the vaporizer is getting the fuel too hot it will cause a Vapor High Limit shutdown.
•The vaporizer is located in the fan/heater unit. It is wrap of pipe mounted inside the fan can directly in front of the burner. It can be seen by looking through the inspec- tion door on the side of the burner.
•To properly adjust the vaporizer a 1/2" wrench is needed. Knowing that the gas can get too hot, you must feel the pipe train before the regulator to check this tempera- ture. This point may be very hot so be careful while checking the temperature. The temperature before the regulator must be warm to the touch. This point cannot be hot, nor can it be cold...only warm. Use the 1/2" wrench to loosen the hold down bracket on the vaporizer. Move the vapor izer away from the flame to cool down the pipe train or move it closer to the flame to make the pipe train warmer.
Troubleshooting: Vapor High
Temperature
•The dryer will shutdown but will probably restart as soon as the computer is reset. This is because the high limit is an auto- matic reset and after the dryer shuts down it allows the pipe train to cool down.
•After the dryer is reset, it will run from a few seconds to a few minutes and then shutdown again. This is because the Vapor High Limit is heating up again as
