The home we bought has a lovely Lochinvar 75 gal DVN 076 gas water heater. Several months ago the flame kept going on and off and from the information received from Lochinvar tech support it was the fault of the control module... I purchased and installed a new one and it worked fine until yesterday when the on and off began again.... I left it off all night and turned the module switch on again this morning and it stayed on for about 2 minutes then began off and on again. btw, the blower motor is on 24/7 and I don't see a reset or switch... (there is no manual). Any suggestions would be appreciated.
