JustAnswer Customer: I'm getting service error code 292.
JustAnswer Customer: The system is mostly not coming on, but it has come on twice in the last two days, since this began.
Pearl Wilson: Assistant: How old is the appliance?
Pearl Wilson: Assistant: Have you gotten error messages before?
JustAnswer Customer: Only a couple of years old.
JustAnswer Customer: This is the first time I've had an error message.
Pearl Wilson: Assistant: Do you plan on doing the work yourself?
JustAnswer Customer: No.
JustAnswer Customer: I have a repairman scheduled for tomorrow afternoon.
Pearl Wilson: Assistant: Anything else we should know to help you best?
JustAnswer Customer: What does the error code mean?
JustAnswer Customer: I just looked it up.
JustAnswer Customer: The system is actually five years old.
airheatman: HVAC Technician: The good news is I can tell you what the error code means.
airheatman: HVAC Technician: The problem is that your blower is having issues trying to start.
airheatman: HVAC Technician: The bad news is that if this furnace has an ECM motor with a bell on end and two sets of wires going to it, you are going to need a Lennox Trained technician with a special tester to troubleshoot to find out why.
airheatman: HVAC Technician: Now on a better note, if unit was registered at time of installation you should have a 10 year parts warranty.
airheatman: HVAC Technician: You may be presented an offer for a phone call for an additional fee.
airheatman: HVAC Technician: Please ignore offer for phone call as I am unable to take a call right now but we can work here as long as needed.
airheatman: HVAC Technician: The offer is automatically site generated.
JustAnswer Customer: A serviceman came out on Monday and "fixed" it, but last night it went out again with a different service alert code, 411.
JustAnswer Customer: He said he tightened some loose wires and we also flipped the breaker, which worked, on Monday.
JustAnswer Customer: I flipped the breaker again today.
JustAnswer Customer: It didn't help.
airheatman: HVAC Technician: The 411 indicates a low pressure lockout.
airheatman: HVAC Technician: This is an indication that we have a refrigerant issue or low air flow across coil inside.
JustAnswer Customer: yet the technician checked all those things on Monday and said they were all right.
JustAnswer Customer: Could it be the thermostat?
airheatman: HVAC Technician: I suspect it still has to do with that motor inside, low or no air flow will trip that low pressure switch.
airheatman: HVAC Technician: Call him back and let him relick his calf so to speak.
