steve, first look at the manual if really it is stated in there that the three blinks indicates an o.u. pcb. second, do you install them yourselves?. im not sure regarding warranty if you install them. normally there should be a qualified installer to install it to cover warranty. again if you install them yourself, double check the wires that goes to the outside unit. make sure each wire goes to its corresponding location. any mis-wiring would may also indicate a 3 blink alarm. if its covered in warranty. they should shoulder the expense if it needs board replacement. i hope i was able to solve your problem.. tnx

I would first check the condensate drain pipe. This can be done by blowing back into the drainpipe from outside. Not to worry it is not dirty or dangerous. Also make sure that your air filters are clean.

SOURCE: Furnace blows cold air, ignitor won't glow.

ok this is going to sound funny but it seems as though the polarity is reversed going into your furnance. to correct this proiblem you first need to unplug the unit and where the cord goes into the furnance at that connection disconnect the two wires. Once theses are disconnected switch the wires .All you are doing is reversing the way the electricity flows into the circut board. I would wager that is the problem

Sounds like you have a bad fan relay, the fan should shut of within 30 to 120 seconds after t-stat is satsified.

Fujitsu airon ASTA24LCC 2 flashes green and red then 5 red flashes any idea what it means


Had similar problem (ie. 2 green & red flashed followed by 5 red flashes - Fan blowing but not cooling ... I also noted that the outside unit fan wasn't going). Tried restarting several time after waiting only a minute or two after turning the mains power off but with no change. So turned the unit off at the mains power and then fired it up about 2hrs later and it was all working fine.

See if your fans and drives are spinning up fast enough, perhaps image a fresh drive if you can; certainly it's time to resolve BIOS state issues from discombobulating the DDR.
Er, how many DIMMs are in there now? 1? Is it good?

I have a Rheem Furance that has turned off. Just a few hours ago the main fan turned off. The Furnace doesnm't light even the draft fan does turn on and then the main fan blower motor turns on. I can hear...


You will need to reset the furnace by turning the power off to it. Then as the furnace tries to light, watch the LED for blinking. Hopefully it will give a code other than 1. Try checking the air filter for blockage, make sure all hoses are free of moisture and any drains are not blocked. Check the air intake and exhaust pipe for sags where water could block it.

The sequence of operation is this:
Thermostat calls for heat, the LED may blink telling you it registers the call. The inducer (exhaust) blower starts closing contacts in the pressure switch (small disc shaped thing), the igniter glows orange (seen thru a small window high up on furnace front), gas valve opens allowing main burner to light, flame travels to all other burners, flame rod senses flame within a few seconds and keeps gas on. Room air blower starts within 90 seconds.

Any deviation or delay in this sequence and it goes into lock-out.

My gloworm micron 50ff is 6 years old and will not always light automatically without me turning the reset button. It will sometimes fire ok without any problem - I have just changed pcb board yet still...


Get a can of air used in the computer industry and use it up by blowing on the pilot assembly and any where you can get the straw into. Next take some steel wool or a scrub pad and polish the probes on the pilot assembly.

Paslode framing nailer 1998 yr. model when engaged wont fire


you have spark and cleaned tool correct, but fan won't turn that freely, if so the fan motor is bad, it should come on when you pull the trigger or move the roller lever for the safety. The fan is about 80.00 Let me know if I missed something and how did you check the spark?
