Customer: ***** *****, I have a Lennox conservator 90 GWB 100 with what we think is a partially blocked heat exchanger
. It cycles through proves the flame but shuts down after 15-30 seconds. Does not lock out but just keep cycling. Both repairman believe it's a blocked heat exchange. How hard is it to clean. I realize I would have to take apart.
JA: Thanks. Can you give me any more details about your issue?
Customer: fan runs half voltage which is one reason we believe it is a blocked exchange. flame looks good, burner was taken out and cleaned 2 years ago, drain tubes recently pluged and after I cleaned them the system will not stay running, just keeps cycling. checked pressure, flues, ect... water will only get to about 120
