The yellow light will fl ash 1 to 4 times depending on the amount of light detected by the cad cell. The burner will remain off as long as the button is held.ĭuring the burner Run state, click the reset button to check the cad cell fl ame resistance range. To reset, hold the button down for 15 seconds until the red light turns off and the yellow LED turns on.Īny time the burner is running, press and hold the reset button to disable the burner. If the control locks out three times without a satisfi ed call for heat or fails the motor relay check, the Lockout becomes restricted in order to prevent repetitious resetting by the homeowner. When fi nished, hold the reset button or remove the call for heat to exit Pump Prime mode and return to Standby.

If necessary, repeat steps 4 and 5 until the pump is fully primed and the oil is free of bubbles. Bleed the pump until all froth and bubbles are purged. At burner start up, click the reset button while the igniter is still on to enter Pump Prime mode. The yellow light will turn off and the burner will start again. When the burner starts, press and hold the reset button for 15 seconds until the yellow light turns on. Unit 3 - 430 Laird Road, Guelph, Ontario, Canada N1G 3X7 Not sure if it is an electronics, fuel/piping related or mechanical issue.Form No. I am just out of ideas and it is about to get very cold here. Interestingly, the heat exchanger is still under warranty (20 year, parts only) and so I am looking for some sane advice.
Beckett 7505p operation cracked#
My oil/heating company which initially told me that the heat exchanger is cracked wants ~$6k to replace the whole system. and checked CO/CO2 levels (flue gas as well as near the vents). He did a draft test as well, vacuumed inside and thoroughly service the burner, i.e., replaced oil filter, strainer, cad cell etc. I had another guy look at it thoroughly and he says the heat exchanger it okay. My oil/heat service company came and tells me that the heat exchanger is cracked (based on draft test). Now, if I reset the burner then it runs for as long as it has to (e.g., 30-60 mins) until the thermostat shuts it off.
Sometimes it recycles twice before locking out.
I turn up the thermostat (Nest) and it starts, runs for a 1-2 mins, goes into recycle mode, starts again, and runs for a few mins and locks out. Guys, I am experiencing the exact same problem with my Beckett AFG connected to a Williamson CHB-105-DD (installed in early 2000s). Does this sound like the control module or maybe the aquastat? Since the burner always starts and runs every time I restart it, I'm convinced it is not the pump or the supply line. If that happens, the burner goes into lockout, and I have to clear it and go thru the recycle sequence again until the burner appears to operate normally. It will run this way for a few hours, or until the operating temperature can not be attained thru 2 recycle sequences (a call for heat might occur during the recycle sequence). After reaching operating temperature (about 190 dg), it shut off normally - no lites.
It then ran thru the recycle sequence (14 blinks - about 20 seconds), and then started again. It then shut off and the recycle lite (2 second blinks) came on. This time I sat there until the burner responded to a call for heat: it started normally, and ran for about 5 minutes. When the boiler reached operating temperature, the burner shut off with no lite flashing on the control module. I went thru a restart sequence again as I described previously. I'm about ready to give up and call a service tech.
