i beleive you did more than that.? you,ll probably find all have a common earth , chech and remove it , clean with a wire brush and replace, also chance the fuse you removed and replacer reguardless of it,s appearence , ensure its put back in the correct location,peter.
CHECK AC AND HEATER CONTROL FUSE. IF FUSE OKAY CHECK BLOWER SEE IF POWER GOING TO BLOWER MOTOR IF YES BLOWER MOTOR MORE LIKELY FAULTY.IF NO POWER GOING TO BLOWER MOTOR CHECK BLOWER MOTOR FUSE ANDRELAY.
Step 2 Check: Fusing Heater Lamp (H1) is open-circuited. <Check Procedure> Check the resistance across both ends of the Fusing Heater Lamp (H1). The Fusing Heater Lamp is open-circuited if the resistance is infinity.
Step 3 Check: Thermoswitch 1 (TS1) is operational. <Check Procedure> Check the resistance across both ends of the Thermoswitch 1 (TS1). The Thermoswitch 1 is open-circuited if the resistance is infinity.
Result: NO Action: Change Thermoswitch 1 (TS1).
Step 4 Check: Fusing Unit Interlock Switch (S2) is operational. <Check Procedure> Check continuity across terminals when the Fusing Unit Interlock Switch (S2) is turned ON. • Across S2-1A and S2-1B • Across S2-2A and S2-2B
Result: NO Action: Change Fusing Unit Interlock Switch (S2).
Result : YES Action: Change DC Power Supply (PU1).
Step 5 Check: Thermistor (TH1) is open-circuited. <Check Procedure> Check the resistance across CN15-2 and CN15-3 on the Fusing Unit side with CN15 disconnected. The Thermistor is open-circuited if the resistance is infinity.
Result: YES Action: Change Thermistor (TH1).
Step 6 Check: The following voltages are supplied from the Master Board (copier: PWBA). <Check Procedure> Check voltage across a Master Board (copier: PWB-A) pin and GND when the Power Switch is turned ON. • Voltage across PJ10A-7 and GND DC24 V when Fusing Heater Lamp (H1) is OFF DC0 V when Fusing Heater Lamp (H1) is ON • Voltage across PJ10A-10 and GND DC24 V when Fusing Heater Lamp (H1) is OFF DC0 V when Fusing Heater Lamp (H1) is ON
Result: NO Action: Change Master Board (copier: PWB-A).
Hello my name is Heath it will be my pleasure to assist you. First thing to do is go to the furnace take off the lower blower door and locate the circuit board turn the power off to the furnace. In the circuit board there should ba a small car like fuse usually 3 or 5 amps check the fuse it is probably blown replace the fuse with the same amperage fuse and then turn the power back on on the furnace and check the operation of the furnace.
if you have incoming power, you may have a bad transformer. those systems run on 24-28v. you can check from yellow wire to yellow wire coming off the transformer to see if you have anything coming out. must check wires coming out of the transformer to each other, it won't register if you check each one individually to ground. hope this helps...
Hi, my name is John. Welcome to FixYa. Make sure that you are getting power to your unit by running the wire to the battery, hot (+) and ground (-), let me know if you still have no power and I will post solution here. Thanks for choosing FixYa....John
