3977393 part# sub is WED6200SW1 the hi-limit thermo is not right

16 posts in this topic

This Cabrio Dryer model #WED6200SW1 has blown the thermal cut-off. The part number they sub is a thermal cut off kit #279816 that does not have a hi-limit thermo that is compatable, because it has a thermistor connection on the hi-limit on the Cabrio. But there is not a #3977393 you can buy seperately, and no kit that has the right high-limit thermo. Any thoughts?

Can you take a close up picture of the old hi limit thermostat?

You have to buy the 279816 kit, but you do NOT use the high limit thermostat that's in the kit, just the thermal cutoff. You still have to buy the hi limit thermostat separately.

The hi-limit thermostat that you posted (with the "thermister" connection) is used in addition to the high limit thermostat - as I recall it is mounted on the exhaust outlet. The Fuse that is in 279816 kit is the same - the one on the element housing.

So for this dryer, Scott, you have to stock the high limit thermostat:

AND the thermal cutout fuse kit:

But you need to mix n' match using the high limit tsat in the first link and the thermal cutout (only) in the second link?

Yup - the thermal cutout is n/a on it's own, it subs to the kit

I found a cheaper solution to my problem. All you tech's out there, make a note of this part number. #SET194 Thermal cut-off kit. It is the same as 279816 kit. Saves about $20 on buying the hi-limit that you will probably never use.

The hi-limit thermostat is attached to the bottom of the Flat Can Element. Whirlpool calls it tje Inlet Thermistor/High-Limit Thermostat. Looks like this:

There is a outlet thermostat on the blower housing.

I gotta get this right.............I cannot find P/N 8577891 being called a Thermistor/ High limit thermostat.. It is just a plain old Hi-limit thermostat..... ( I may be incorrect, but never wrong )......On the parts break down, Item 8 is listed as Thermostat, Hi-Limit.......................A Thermistor is a resister the will change its value with heat ( or cold )........... On the blower housing , Item 40, P/N 8577274, IS listed as a thermistor............... K-dog is correct on you cannot call it a thermistor by it's connection............. Let me drag my crate over and stand on it....... Fuses do not "blow"....... fuse's 'fail open'......Dynamite blows..........The circuit is either open or closed, ( or depending where the quarter fell into the wires....'shorted' ) ....Let me get off my crate............................Check the wire diagram for the wires attached to p/n 8577891, does it indicate a thermistor????..........I would post a picture of a thermistor symbol, but alas, I do not know how.......

Appears they only call it a High Limit Thermostat but it is in fact a High Limit Thermostat and a Thermistor, see the small two pin connector on top and the bottom picture shows the thermistor that would be in the air flow along with the sensing portion of the high limit t-stat.

The RepairClinic picture is the first one of these I've every seen.
