GE Profile gas dryer

I have a GE model DPXR473GWOWW that has melted polyester on low setting from day one. The dryer was converted to use propane and I notice a very yellow flame. Since the air mixture is in a fixed position is there any way to adjust the gas valve to achieve a blue flame? Or is a yellow flame normal in this model?

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

Based upon the information you provided, the burner is overgassed. Which means the flames are too large.

This condition happens when an appliance is converted from natural gas to propane. The most likely problem is the natural gas burner orifice was not removed and replaced with a propane sized orifice. The 2 orifices differ greatly in the size of the hole.

To correct the condition, remove the burner assembly and then remove this existing orifice. Install a propane sized orifice rated at the BTU size of the dryer.

Another item that may have been overlooked during the conversion is the conversion of the regulator. The regulator is built into the gas valve. Most gas valves can be convered simply by turning over the cap installed on the regulator.

best bet is to remove the entire gas valve, take it to the local appliance parts store for the conversion. Be sure to write down and take the model and serial number of the dryer with you.

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

An excellent source for orginal replacement parts is your local retail appliance parts store. Appliance parts dealers carry replacement parts for all appliances. Parts dealers are listed in the phone book.

DRYER SERVICE TIP:
It's always adviseable to clean the entire exhaust venting system during any dryer maintenance and or repairs.

Regards & Good Luck
