Old Carrier furnace: spark igniter
Old Carrier furnace: spark igniter
Greetings, I gotta Carrier upflow furnace (58GS075-2), made in '83. It's old, but everything works except something in the spark igniter circuit. I'm having trouble figgering what. I replaced the gas valve 10 years ago, the rest is original equipment. Spark igniter (BDP model 733B) has 3 lo-voltage wires (white, yellow, red) connected. Electrode (looks like Penn model j996) has 120 v. wire (red) attached. Other end of red wire is hard-wired into black 2 x 3 x 1 " box labeled 'spark ignition'. Tstat calls for heat. Vent damper does it's thing. Pilot gas flows, and the igniter is supposed to spark, but I can't measure any voltage from the electrode to the pilot shield (or to the gas pipe). I once lit the pilot with a match. It went thru the cycle OK: fired the main burners, blower, etc. I can't even get the lo-voltage connector to the igniter to separate. Some parts of this furnace look like they were engineered in Outer-Space. Of course, I'm not a "Pro" ... The igniter electrode *looks* OK. The wiring diagram looks incomplete: I can't find the 120 v. to the spark ignition box. How to test the spark ignition (black) box? The spark igniter circuit(s)? Any/all help/advice much appreciated. Cheers, Puddin' -- ************************************************** **** *** Puddin' Man PuddingDotMan at GmailDotCom *** ************************************************** ****; |
