From https://www.justanswer.com/ythi JustAnswer Customer from San Antonio, TX: Hello, my Lennox furnace is showing code E312. JustAnswer Customer from San Antonio, TX: The compressor is running at normal speed but no air is being pushed through the system. JustAnswer Customer from San Antonio, TX: The thermostat continually reads ‘stage 2’ Pearl Wilson: Assistant: What happened just before your Lennox furnace displayed this message? JustAnswer Customer from San Antonio, TX: nothing out of the ordinary. 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: It started late last night. JustAnswer Customer from San Antonio, TX: I’ve only tried turning off and on from nest thermostat Pearl Wilson: Assistant: Anything else we should know to help you best? JustAnswer Customer from San Antonio, TX: the display also reads C2 airheatman: HVAC Technician: The E312 is an airflow error code. airheatman: HVAC Technician: Blower is not moving sufficient air. airheatman: HVAC Technician: Check and make sure filter is clean, no dampers are closed and blower is working. JustAnswer Customer from San Antonio, TX: The filter is clean, no dampers are closed. JustAnswer Customer from San Antonio, TX: I have the system service every 6 months. JustAnswer Customer from San Antonio, TX: No air is coming through at all. JustAnswer Customer from San Antonio, TX: Is there anything else I can do before I call for a service visit? airheatman: HVAC Technician: Not really. airheatman: HVAC Technician: This one has what is called an ECM (Electronically controlled motor) which requires an an expensive diagnostic tool to troubleshoot. airheatman: HVAC Technician: https:/www.amazon.com/Variable-Speed-Zebra-ECM-Diagnostics/dp/B008HQ6P26/ref=asc_df_B008HQ6P26/?tag=hyprod-20&linkCode=df0&hvadid=312155908282&hvpos=1o5&hvnetw=g&hvrand=*38&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9012943&hvtargid=pla-572566358572&psc=1 It is also very probable this will be under warranty. airheatman: HVAC Technician: If you are not ready to rate please keep replying so we can wrap this up. airheatman: HVAC Technician: You have paid for your consultation. airheatman: HVAC Technician: I AM NOT PAID for my time until you rate. airheatman: HVAC Technician: If you stop replying and do not rate, the question will “Time Out” and neither of us benefit from the money you spent. airheatman: HVAC Technician: Thanks. airheatman: HVAC Technician: Remember that you can still follow up for 30 days after rating at no additional fee. airheatman: HVAC Technician: You should see 5 stars across top of page for rating. airheatman: HVAC Technician: Until you rate I will get notifications that I need to finish answering the question. airheatman: HVAC Technician: Bonus is always appreciated but of course not required. airheatman: HVAC Technician: Thanks again. JustAnswer Customer from San Antonio, TX: Thank you. JustAnswer Customer from San Antonio, TX: I will leave review. airheatman: HVAC Technician: Thanks again JustAnswer Customer from San Antonio, TX: You're welcome. JustAnswer Customer from San Antonio, TX: Thank you as well JustAnswer Customer from San Antonio, TX: Good morning After we communicated, there was ice in the compressor and feed going into the house. JustAnswer Customer from San Antonio, TX: The tech came out yesterday, ran tests and said everything was fine. JustAnswer Customer from San Antonio, TX: One thing he said he found was that when our system was shutting down, our Neat thermostat would read ‘Stage 2 Coolimg.’ That being said, he disconnect that from the Nest as he said the compressor isn’t a 2 stage model. JustAnswer Customer from San Antonio, TX: What can be freezing up things? airheatman: HVAC Technician: Two these cause icing. airheatman: HVAC Technician: 1. airheatman: HVAC Technician: Low air flow 2. airheatman: HVAC Technician: Low refrigerant or restriction in refrigerant The tech is wrong. airheatman: HVAC Technician: Everything is not OK if it ices. airheatman: HVAC Technician: It is possible that the motor was running when he was there but is quitting or there is a metering JustAnswer Customer from San Antonio, TX: He’s definitely wrong. JustAnswer Customer from San Antonio, TX: When you say ‘restriction in refrigerant,’ does that mean the refrigerant is not cycling through the system? JustAnswer Customer from San Antonio, TX: What is metering? airheatman: HVAC Technician: Yes. airheatman: HVAC Technician: At each coil there is a metering device which meters the amount of refrigerant as it goes into the coil. airheatman: HVAC Technician: These can stick closed or partially closed causing a restriction. airheatman: HVAC Technician: 99 per cent of these TXV metering devices are imported from China and Mexico.
