Clydesdale wood insert thermostat .. replacement ?

[Sean McGillicuddy]

My Clydesdale wood insert is getting slower and slower to turn the fan on... do you think the thermostat is going ?
Do the make a lower one so the fan will turn on faster?
Were is it located ?
Thanks

Open your owner's manual & read it. The answers are in there.

 

[Sean McGillicuddy]

Good idea … Now were is that manual … That's the problem ..

 

[Sean McGillicuddy]

Found the manual and part info on line ..I was wondering if anyone just did this and had some pointers..

 

[DAKSY]

OK. Have you vacuumed everything in the blower area?
Does the thermo disk look clean?
Is it making solid contact with the stove body?

 

[Sean McGillicuddy]

Hmmm would you happen to have a pic...

Not sure which model Clyde you have, but here's the latest manual.

 

[Sean McGillicuddy]

I think this is what your referring to
C 34 7000-301 SWITCH: T'STAT,BLOWER,TUC 1/WIN/DVI 32
Do they come in diff temps like the ones for your car ?

 

[Sean McGillicuddy]

Hmmm $60 to replace this ..what would happen , if I tried to clean it ..not that is dirty ..it's tight against the casting ..

These snap disc thermostats are common and sell for under $15 typically unless proprietary. What you need is the rating of the switch. Clean it off. Do you see any writing or numbers on the side?

 

[Sean McGillicuddy]

I'll take a look!
Thanks

Yes 21500 F120-15F 7000-3

120v thermal switch 21500 F120-15F 7000-3 - Google Search

I do not know what your temps are but the numbers MAY indicate NC (on) at/above 125*f and NO (off) below 105*f

Amazon product ASIN B0026RTEZC
Youll find it cheaper if you shop around AND *** The switch MUST be rated for the voltage used, Presumably 120V***
11.95 fs over 25

Yes, that is right for temperature. It must be rated for the amperage load of the blower(s). They come in different packages. Some are button faced like the one you posted and some are flush-faced. That will be easy to determine when it's removed.

So my question should be .. do these slowly stop working ..or what causes it to not work as it did new?
Is there some thing I should do to get it to turn on faster,,it takes along time to turn on the fans.. Is this what would cause the delay? I'm afraid to replace this and see no improvement..

It could stop operating properly due to a lack of heat transference (loose mount or debris behind steel) or because the bimetal element has fatigued, poor guality, overfiring, or corosion, etc. Ive seen insect debris in places it doesnt belong, such as switches and relays which burned up contacts or prevented them from making contact. Ive even seen an alternator full of stink bugs which caused the brush surfaces to get all messed up.

It could also be your rheostat. I’ve had to replace mine twice on the Clyde. Shop around you can find them on Amazon a lot cheaper than the fireplace stores. Easy to replace.

 

[Sean McGillicuddy]

The thermostat is on the way ..I'll report back when I have it in and running ..

 

[Sean McGillicuddy]

It is in …. and no difference …

If you already are having fires, you can test the snap switch setpoint with an ohm meter or volt meter and use a digital therm to observe when it cuts in and off.

If you can remove the switch, test the setpoints with a hair dryer and ohm meter and digital thermometer. If the switch is out of spec's by 10%?, replace. The actual heat transference and stpoint may vary when installed but should be close when isolated by removing it from the stove.

That is beyond my understanding..

Replace the thermostatic snap switch if the switch is:
1. Properly mounted
2. Inner stove area adjacent to the switch is clean/clear in order to promote the best heat transference.
3. Properly wired.

1. Properly mounted yes
2. Inner stove area adjacent to the switch is clean/clear in order to promote the best heat transference. yes
3. Properly wired. Hmmm

3. Properly wired …. is it positive sensitive ( have I switched leads ) ?

Please receive this in the gentlest of tone; Electricity can cause fires, burns, death, and property loss. I strongly suggest you consult an electrician or an appliance repair man to correct this issue.
