STEP THREE: 

 

   A multimeter / voltmeter is required to    

perform the following test  


          A 
 
 

               

Ω 

WARNING! 

           TURN OFF THE CIRCUIT BREAKER BEFORE  
               PROCEEDING WITH THE NEXT TESTS. 

 
 
 
 
 
 
 
 

NOTE: BE SURE THE ELECRICITY IS TURNED OFF TO THE UNIT 

Ω

Set the meter to the 

single ohms setting. 

The Ohm Symbol 
(The upside down horseshoe)

 

Do not measure continuity, this will not work. 

Remove the front cover of the unit. At the end of the black heater body, there are 
two threaded silver rods with brass nuts on them (Where the wires connect). Take a 
reading of the ohms value between these two rods and write it down (See diagram 
below).

 

 
 
 
 
 
 

 
 
 
 
 
 
 
 

 

If the reading is less then 20 ohms on the  
single (Rx1) scale or the (Rx10) scale, then  
the element is good, if it is much greater  
e.g. 10,000 ohms or if you get a reading  
on the Rx1k, you will need to replace the  
element. To do this, contact Technical  
Service at 1-800-334-3393 for the  
replacement elements. (Please write down 
the resistance value, before contacting  
Technical Services. This will be very useful to 
us.  Also have the order ref. and serial  
number for your unit available for Technical  
Service.)
