We have a Lochinvar Energy Rite gas heater. This is our 5th season with it and up until now it has performed flawlessly.
Now, when we start the heater, it says Prepurge, and then you can hear the fan start, then it goes through the Prepurge cycle 4 times and then turns off with the message on the display: "Ignition Failure Lockout" According to the manual, it will do the Prepurge 4 times and if it doesn't see a flame, it will display that lockout message. Normally, when functioning correctly, it will Prepurge, fan turns on, then goes to Postpurge and then it's on.
From my understanding the way to reset the heater is just to power it off and then back on. There is no reset button on the display, in normal mode, or in the Setup or Service menus. We did power it off and back on, but no luck, still the same lockout message.
We do have someone coming out but not till next Tuesday, and just wondering if anyone has any ideas on this. Thanks.
