JustAnswer Customer from San Antonio, TX: I get error codes 274 and 250 on my Lennox el296uhv gas furnace
Pearl Wilson: Assistant: What happened just before your Lennox furnace displayed this message?
JustAnswer Customer from San Antonio, TX: Also a475
Pearl Wilson: Assistant: How long has this been going on with your Lennox furnace?
Pearl Wilson: Assistant: What have you tried so far?
JustAnswer Customer from San Antonio, TX: Ok I think I screwed it up, did not take cover off fan when started up last weekend, furnace was still holding temp when I got here today, but error codes, so I shut it down waited for fan outside to stop running and started it up again, now it doesn't heat
Pearl Wilson: Assistant: Anything else we should know to help you best?
JustAnswer Customer from San Antonio, TX: When they shut home down last fall I think they just turned main breaker off, I don't know if that matters
JustAnswer Customer from San Antonio, TX: Ok
BillyHvac: Journeyman HVAC Tech: Hello, Those error codes went into the que when they happened, but the issue is gone.
BillyHvac: Journeyman HVAC Tech: Both codes relate to overheat sitiations, so the codes were stored in the archive.
BillyHvac: Journeyman HVAC Tech: If it were a "lockout" situation the furnace would be disabled and you would have no operation.
BillyHvac: Journeyman HVAC Tech: Remember to change the air filter, but if the cover is off and the unit is holding temp currently, the codes are history and not current.
BillyHvac: Journeyman HVAC Tech: Billy disregard phone call offers as those are not from me but computer generated.
JustAnswer Customer from San Antonio, TX: No it is not working now after I shut down and restarted
BillyHvac: Journeyman HVAC Tech: did you wait the 5 minute reboot time for the units to "discover" each other?
JustAnswer Customer from San Antonio, TX: Not 5, but I can try
JustAnswer Customer from San Antonio, TX: Ok power off to the blinking codes is that good enough or should I shut down main breaker
BillyHvac: Journeyman HVAC Tech: That should be fine.
BillyHvac: Journeyman HVAC Tech: No need for main breaker cycle.
BillyHvac: Journeyman HVAC Tech: Is the unit back to stable?
JustAnswer Customer from San Antonio, TX: Waiting for 5 minutes
BillyHvac: Journeyman HVAC Tech: standing by
JustAnswer Customer from San Antonio, TX: To power back up
BillyHvac: Journeyman HVAC Tech: ok
JustAnswer Customer from San Antonio, TX: Ok power on just blinking red dot
JustAnswer Customer from San Antonio, TX: Thermostat is off
