"PF" message on Kenmore Gas Dryer

Since we moved, I cannot find owners manual. We just got a "PF" message on the electronic LED display. I am guessing it stands for partial flow, and plan on cleaning the duct work today.
But I would like to know for sure.

After looking in the attic, the duct seems to be very long for a dryer. The laundry being in the front of the house, it goes up into the attic at the front of the house but then heads up to the back roof surface at a 45 degree angle. I suppose they did not want the vent to be visible from the street. Do you know of any inline dryer vent boosters?

I probably should just eliminate about 20 feet of the vent and go straight out the roof above the dryer. But I have not seen a good roof dryer vent cap. The one on the back roof does not allow for cleaning.

Thanks

 

Hello KBright and Welcome to our Do It Yourself Web Site and my Gas Appliances forum.

You could do a simple test to determine if there is a restriction within the exhaust venting system. Remove the entire venting system from the dryer at the back of the appliance.

Unplug the dryer for several minutes to rest the computers main board etc. Then, without the venting system attached, run the dryer and determine the results.

If the same code appears, {it's not necessarily but still could be} a venting restriction due to the length of exhaust run, number of elbows etc. The ventings piping may be restricted and or the cap too restrictive etc.

Another possibility could be a restricted gas supply flow. Check the shut off valve on the supply pipe behind the dryer. The valve itself may not be turned on fully, restricted and or defective.

The acutal supply of gas could be restricted and or of low volume. In this case you may need to contact the gas supplier and or gas utility company.

Suggestion:
Read the manufacturers online web site for product information, problem solving methods, disassembly instructions, repair proceedures, pictorials and schematics, may be available online.

Hi all,

"PF" often means Power Failure....esp after unplugging and reinstalling the power. Does the dryer have a reset/clear/off button that may be pushed to see if the PF disappears??
