ONE ZONE OR SOME ZONES WORKING AND ONE OR SOME ZONES NOT WORKING

If you have any questions you can email me

Start at the #1 solution then #2, then #3 etc.

#1   Run each zone manually, list zones than are not working

#2   Start at controller, ( you will need a multi-meter for the next few steps, they can be purchased at hardware stores for

around $15, make sure it will read voltage and ohms)

STOP!  IF YOU DO NOT KNOW HOW TO USE THESE METERS STOP HERE AND CALL A SERVICE TECHNICIAN,

YOU CAN DO MORE HARM THAN GOOD!

#3   Check the voltage to to the zones not working,  place the red lead of the multi meter on the  valve terminal and place

      the black lead on the common terminal (usually labled “c”). The correct voltage should be around

      24 vac. If  you get 24 vac goto # 4, if  not  repair or replace controller.

 

#4   Using the multi-meter set to “x10” ohms  (MAKE SURE THAT THE CONTROLLER IS UNPLUGGED AND

TURNED OFF TO AVOID DAMAGE TO THE METER)    Place the red lead on the station number not working, place

The black lead on the common terminal.  If the reading is less than 20 ohms replace the selonoid on the valve.

If the reading is between 20 ohms to 90 ohms,  goto #6.  If the reading is over 90 ohms goto # 5.

 

#5  Check the wire connections at the valve in question, if the readings are still above 90 ohms, there is a bad splice, or broken

field wire to the valve.   (TIP:  run a new wire above ground from the controller to the valve in question, first check

the station wire, then the common wire, this will tell you which wire is bad.)

If you do not have a line fault locator, just replace the bad wire, or call a service technician they can usuallylocate

The break for under $100.  If it is not too long of a run of wire most times it is more cost effective to replace the wire.

 

#6   If the valve has a flow control knob make sure it is open (usually turning counter-clockwise).  If flow control

is open replace or repair valve.    Valve Repair
