Hi All, I have a Regency GCI60 that was making a high pitched sound on start up. I pulled it out and oiled the bearings on convection fan and oiled the combustion blower. I then put the unit back and I'm getting a #2 light flashing which would be a vacuum issue. Did a thorough cleaning including the exhaust pipe, checked the vacuum hose and gaskets. Everything seems correct, but I'm still getting the #2 light with fan blowing at high speed as soon as I turn the unit on. Any suggestions?
Welcome to the forum. I have no knowledge about that unit, but I'm sure some of the others here will chime in. BTW, you didn't say if oiling the motors stopped the high pitched sound.
Thanks, sorry, yes, I think it did. Unit isn't fully firing back up, but the fan comes on and sounds normal. Trying to get into the other side of the combustion blower now to see if I can get it off and clean it out more. That's the only thing I can think to do since I cleaned the exhaust port and now I've cleaned where the exhaust channel sensor it. I just haven't fully pulled the exhaust blower to clean it out. Was a little worried about being able to get it back in place.
The exhaust blower is what creates the vacuum for the vacuum switch to operate, so yes, getting it out & giving it (and the nearby exhaust passages) a good scrubbing probably is a good idea. BTW, did you try bypassing (temporarily only) the vacuum switch? Just pull both terminals and connect them together. Fire up the stove up & see if the light stops flashing. I'm assuming that the switch is in the closed position when the blower is running and there's normal vacuum.
Didn't try that yet because I wanted to get to the problem if I could, but that's my backup plan. I have the blower unbolted, but can't find room to slide it out. Hopefully someone who knows this until might have the answer. Can't think of anything else to try.
Greetings JasonG, Welcome to the forum. I don't own your stove, but took a quick look on the Regency website, nice stove! The site has a detailed manual section for your stove, below link is for the technical manual download: GCI60 Cast Iron Pellet Stove Insert | Regency https://assets.regency-fire.com/get...ce7-6b3707db5891/Tech-Manual-English-(1).aspx +1 with imacman - if you are confident the vacuum hose is connected to the stove barb <-> and vacuum switch, temporarily (bypassing) the vac. switch by connecting the (2) terminal connections together ( aka: "hotwiring" the stove ) may help in determining if the issue is the vac. switch. A Digital Volt/Ohm Meter (DVOM) with continuity test function is also very handy to test the vacuum switch, FYI. Ensuring the internal stove passages are clean, the gaskets look good / intact, the Damper control hasn't been disturbed, are other checks I would do also, if here. I hope the information is helpful to you. Regards, Rob
Appreciate the help. I couldn't get the blower fully off, but I was able to get a vacuum in there pretty good and that seemed to do the trick. Impeller spinning much easier so must have just been clogged up. Thanks again!
I'm a bit confused. To service the blower, you need to slide the insert out. To do a proper 1 to 2 times a year major cleaning of the stove,and the flue, you must slide the insert out. Sounds like this has not been done, and a ton of ash may be stuck in there behind the combustion blower.
I did pull it out and cleaned around the blower, but I wanted to try and get the blower completely off to fully clean it out. It was difficult to get a vacuum hose all the way into it. I unbolted it, but there physically wasn't any room for it to slide out. I'm still not sure how you would get it out without taking the entire housing apart, but I was able to spin the impeller and vacuum around it enough to get almost all of the ash. I think that was the issue because after I did the #2 light stopped and it works well now. Having another issue with the control panel, but I'll start a new thread. Thanks again everyone, appreciate the help.
