Moon_K - #1- DO you have a ( VOLT-OHM meter) IF not you can get a reasable cost one at Lowe's OR HOME DEPOT IN the electrical dept. Get one that you can go to 220 VOLTS A>C>(#2-) UNPLUG THE DRYER CORD FROM THE WALL> PULL THE UNIT OUT FROM THE WALL OS YOU CAN GET IN THE BACK SIDE TO WHERE YOU WILL HAVE TO BE ::} ( #3_) You will have to remove the control panel to get to where you can test the -THERMOSTAT< START SWITCH<TIMER SWITCH.:: OK NOW set the volt ohm meter to RX1 SCALE,( #4A)
TO test the thermostat- Disconnect both of the leads ( WIRES) comeing to it , CLIP OR hold the probs from the vmeter ,one to each wire terminal, TURN THERMOSTAT TO ANY SETING EXCEPT ( Fluff dry) IF meter reads ( ZERO ) the thermostat is good ,if it reads HIGH, it is faulty,REPLACE< REPLACE WIRES YOU REMOVED:
#2b)- TO TEST START SWITCH_ DISCONNECT THE HEAVY WIRES FROM THE SWITCH_ CLIP METER PROBS TO THE TERMINALS< PRESS the SWITCH BUTTON IF meter reads ZERO OHMS, SWITCH IS OK IF it reads high,IT IS DEFECTIVE,REPLACE,REPLACE WIRES YOU REMOVED:
#3C)- TO test the TIMER:: Disconnect one of the wires ,clip a prob to each terminal, TURN TIMER TO NORMAL DRY
IF METER reads ( ZERO ) ohms ,it is good,if it reads HIGH,it is DEFECTIVE <REPLACE ;; REplace wires you took off( #3 ) - TO test the heating element for GROUNDING- DISCONNECT BOTH WIRES < Clip or touch a prob to ONE of the terminals and the other prob to the metal duct the element is in ,IF meter reads HIGH it is OK,IF needle swings toward the low side it is defective ,REPLACE
(#4D)-TO test the heating element- TOUCH or clip a prob to each of the terminals on the element ( WIRES STILL DISCONNECTED) IF meter reads between ( 8 and 20 ohms )element IS OK, IF it reads higher it is defective ,REPLACE,REPLACE WIRES NOW::.
( #5E)-TO TEST THE HEAT PROTECTORS-DISCONNECT ONE OF THE WIRES TO IT , CLIP THE PROBS TO THE TERMINALS < IF THE METER READS ( ZERO ) OHMS IT IS GOOD IF IT READS HIGH< REPLACE ITS FAULTY.( NOTE) -Some units have three wire protectors - IF yours does then touch or clip the probs to the two outerr terminals, ALSO LOOK ON THE REST OF THE OUTGOING VENT FOR ANOTHER PROTECTOR:: HOPER THIS gets you going & helps , LET ME know;; HAVE A GOOD DAY AND GOD BLESS;; F.B.E.
