I have a 4 year old Keeprite EnviroPlus 90 gas furnace.
It is working well, exceppt that it recently developed
a condensate/water leak in the exhaust power vent motor assembly.
It seems that the condensate dripping back down the exhaust pipe is
leaking out through the plastic assembly at different points.
My furnace company just came in and replaced this vent motor
assembly with a new one, and guess what, it also leaks,
at a different place.. It has been installed correclty.
It seems that the plastic housing is joined together with clips and
a gasket of some sort. Is this assembly troublesome for others?
I need to place a drip tray in the blower compartment below to catch
This is the older style 'GCK' or 'GNK', right????
If so, the blower assembly is sealed very well from the factory. However
this assembly is installed to the furnace by means of a 'drain transition'
It has two drain ports that protrude into the assembly (one for
upflow/downflow and the other is for the horizontal application), these have
special seals that seal the inducer assembly to the transition. These should
have been changed with the new assembly (they come in the inducer kit). If
your furnace is operating at a high Delta T, these special little seals
become brittle and basically desinagrate. The water would look like it was
coming from behind the inducer assembly if that was where the water is
coming from. There is also a seal around the inlet port of the inducer, this
is also in the new inducer kit (normally it doesn't need to be replaced).
So find out where the water seems to be coming from and I'll likely be able
to tell you were it is coming from.
The model #, serial#, and the installation application (upflow/downflow or
horz.) will aid in the diagnosis.
(or send a picture of the furnace leak to my e-mail, that will solve this
Let us know.
BTW, they need to secure the blower before they connect the outlet piping.
If the piping is applying pressure to the assembly, it may not get seated
Thank You for the quick reply..
It is a GNK100xxxx model.
I was there when the repair man replaced the blower assembly. We moved
an "O" ring from the old assembly to the new one.. Also a light
colored plastic restrictor piece at the center of the "O" ring opening
needed to be moved from the old assembly to the new one.
I have a blow up of the parts right here, we replaced the Blower
Exhaust squirrel cage assembly with attached motor.
Now I had a very good look at where the leak is coming from,
I can see droplets of water hanging off the very bottom of this new
blower assembly.. They pool up and drip onto the sheet metal just
below and eventually enough water accumulates to drip down
to the lower level with the huge blower..
The assembly which was replaced has steel clips at 3 inch intervals
all around. The leak seems to originate right between the bottom
3 clips of the assembly.
Everything is bolted on good and tight..
I'm not sure what you are referring to , the "inducer".
We replace dthe motor shroud assembly ahead of the "transition"
assembly. is ok, looks to be dry all around.
Hope this makes some sense...
I have recieved the e-mails and pictures....
By your description of the problem, you need to lose the maintenance guy and
hire a REAL HVAC Technician.
Have them come out and find, fix, and correct any other issues that may be
Cause, one thing is for sure.......your 'maintenance guy', HAS NO CLUE!!
Seriously, get the problem fixed right and soon....before you have some real
issues with the condensate rusting all the metal components!
