    One Yr Old Rheem Malfunctioning

    Model RRPBL030JK06X, 14 seer, 80% AFUE, R410A, Natural Gas Heat, Electric Cool. Professional installation 8/2006.

    Current overnight temps 48F, daytime temps 78F. Set thermostat for 69 to come on at 4am (Heat + Auto Fan). I wake up at 6am to find the house is 62 and the heater is not running. I switch the unit to off then back to Heat and:

    Relay on thermostat clicks
    Unit on roof hums
    Fan does not start
    If I flip the fan from AUTO to ON, it blows cold air. Then flip it back to AUTO and it never starts back up, just hums. Finally at 10:30a it started up and began to blow warm air.

    This is intermittent. It can work fine for days, then one day just won't run right. Sometimes I notice the unit will hum for like 15 or 20 minutes or longer before it starts up. Usually it only hums for like 3 to 5 minutes.

    I want to get the installer out to inspect it, but if it won't malfunction when he is here what can be done?

    I believe you mean the RRPL-B Series, correct? http://www.rheemac.com/products/Prod...icModel=RRPL-B

    Sounds like you need to re-program your t-stat.

    Had a unit drive me nuts once and it ended up being the draft inducer motor hanging up and finally at some point it starts up. Have the tech barely turn the motor and feel for egg shaped bearings etc.

    I had a 90 Lennox furnace one time that wouldn't heat above 72. The people wanted it at 75. Usually only at night when coldest outside. I would go to house, it would fire up and run perfectly. The house would heat up to 75 no problem. A few days would pass and they would call complaining. I tore that furnace apart. I decided I would try to heat the house up to 85 one day. After about 1.5 hrs of staring at this stupid furnace, it did it. When the pvc was run through the roof and the roofer wrapped the lead around the pipe to seal the roof (tile roof & new construction) they left a little area of lead partially covering the exhaust. The furnace would run for a while until it built up too much back pressure on the draft inducer motor and shut down on the pressure switch. I climbed on the roof and folded the lead down and haven't been back for that problem in 3 years now.

    The next time it does it.

    Don't turn the stat off. Call the installing company back out. It has diagnostics.
    If you Turn the stat off you reset the faults. And they won't know what the failure code is.

    How many times must one fix something before it is fixed?
