View Full Version : Munchkin F09
04-07-2008, 07:16 PM
Good evening everyone. I have a Munchkin throwing the F09 code. I have cleaned the spark ignitor and the flame probe, and the spark does spark and I do get a flame, but it goes out very quickly. I have been getting it intermittently over the winter but I can always get it to restart. I think it may be restarting itself without me noticing also. Yesterday I took it apart and cleaned the coils with CLR. I'm kind of thinking the condensate drain may be clogged, for lack of better ideas. My question now is where does the condensate come from? Inside the coils? I can't find a place the water would drain out. Will I be able to find the drain from the inside? If I pour water inside the coils will it drain out the condensate tube? Thanks in advance for your insights, it is greatly appreciated. Dave

Have you called HT yet? These units are nice when they're "out of the woods", but several things can go wrong. Do you know how to 'blow the condensate" out? I'm not cool with getting all technical on this line, can you post on the pro forum?
There are several tricks that can be done. I'm assuming you set this up with an electronic analyzer? What was you CO on high fire? Is this nat or lp?

Hi Gary, Thanks for the reply. I spoke to HT this morning. It is a three year old install. HT told me to blow into the condensate line with compressed air, among other things. It is natural gas. I am a homeowner but I understand most of the technical things you might say. I'm not sure how or if I can post on the pro forum. I am not sure if the installing plumber set it up with an analyzer or not, but I don't have one and I can't answer that particular question. I assume you have to get the unit running to analyze the CO, correct? Thanks! Dave

I'm sure you're very talented and handy, these units should be looked at every year with an analyzer. There are several tricks that can be done to spank these units into submision, but w/o an analyzer it's just not a good thing trying to wing it. That's where we're at nowadays. It really is best to get someonhe in there that knows this thing.

I agree, but that isn't going to help me get it going tonite!

No DIY, read the forum rules. The reasons are not that we want to be A holes about this, but we don't want to give advice, only to see a report on the news of some one who got their face burned off, CO poisoning, or electrocuted. I know times are tight on the $, but you should really call a qualified HVAC pro. Surly there is a local co that can come out tonight?

I understand, I've worked with plumbers at different points of my life, I do understand the risks. That being said, I have the unit apart and I do intend to figure it out. I'm sorry if I violated the rules, I'm not sure I have but sorry if I did. Thanks! Dave

Well all I can say is best of luck. :)

Thanks! It is now going, but I do need to get a guy with a combustion analyzer in here to set it up correctly. Anyone have any good central MA recommendations? I am just outside (north) of Worcester. I know there is a guy in Webster and Leominster according to HTP.
I am still alive with all my eyebrows and other facial hair intact. I did once blow up a truck in my dad's garage, but that was in High School, I'm much more careful now...

Good that you got it going.
As for finding some one try posting in the Residential HVAC. There are a lot of good guys here.
