Product review (5 stars): Dryers works perfectly after installation of flame sensor
My clothes dryer was not drying the clothes properly thus indicating that it broken and need to be fixed.  I check and see that the average cost to have an appliance repairman to come out and repair it would be $250.  At that price, I decided to fix it myself.

I heard that the most common cause is the valve coil going bad so I check the cost of a valve coil.  It ranges from $15-$30.  I thought that is not too expensive just to buy a new one and replace it.  When I actually talk to a supplier, the cost turns out to be $100 because my dryer is a very old model.

At that price I decided that I better diagnosis first before spending $100.  After taking the dryer apart and testing the flame sensor, I notice that the flame sensor did not shows any continuity.  The Multimeter shows OL(Open Line), thus showing the there is no current flowing through the flame sensor while connected.

I decide to replace the bad flame sensor first before spending $100 for a valve coil.  Ebay had one for $16 and I order it.  After sometime, I finally receiving it and replace the flame sensor on my dryer.  Now my dryer works perfectly.

I decided to check on Amazon to see if they have this item and they had it for $14.5 and it qualify for prime 2 days free shipping.  I could have order it from Amazon and get it in 2 days for free with my Prime Amazon membership, thus would have been able to use my dryer in 2 days instead of having to wait for a long period before receiving the flame sensor from an Ebay vendor, resulting in not being able to use my clothes dryer for quite awhile.

Again I should have check on Amazon before looking elsewhere.  But who would have thought that Amazon would have a flame sensor for a clothes dryer.
