Hey Seahag...little help in the galley please
 

Have you ever had any problems with a thermocoupler on your force 10?

My broiler keeps shutting down. Maybe just a stuck electromagnet???
Do you know what voltage they are suppose to make so I can check it out
with a meter?

Thanks

Joe

Joe,
If memory serves me correctly, a thermocouple with no load should read about
25 millivolts. If you have the screw-in adapter that allows you to check
voltage while under a load, it should be between 10 and 15 mV. Many years
ago I worked on thermocouple systems, and did a test we called "listening
for thud" Place an inline voltage access adapter in the circuit and test
thermocouple output voltage under a load. While the pilot is operating
normally, blow out the flame. Place a screw driver or other "listening"
device against the gas valve and the other end against your ear. When the
pilot valve closes, you'll hear a "thud", which is the solenoid losing its
ability to hold back the force of the spring (i.e., the pilot gas valve
closes). Thud shouldn't happen above 15-17 millivolts. If it does, and you
have clean and tight electrical connection, replace the valve. If the
voltage is low or below 10 while under a load, replace the thermocouple.
This assumes that the pilot flame is adjusted properly and hitting the tip
(about 1/3 of) the thermocouple.

If you don't have the adapter, but you do have a good millivolt meter, then
see what the voltage output is with the electrical end of the thermocouple
disconnected. It's not as conclusive as testing under a load, but it will
probably tell you what you need to know.

If you don't have a good meter, thermocouples are fairly inexpensive and it
won't hurt to replace it as your test.

Wow, in 16 years I've never had one fail...knock wood! The
manual sez 1.5 millivolt. Before you tear it out make sure
your pilot flame is strong enough to warm the tc. I've had
crud from poor propane (or the jet needs a poke) block the
flame from time to time.

I just had a chunk of the broiler ceramic fall off, but it
still works fine!

Thanks...1.5 millivolts is a big difference from 25 mv's.

Guess I'm going to have to get me a manual.

Scout,

Joe is talking about a Force 10 broiler. I don't think there is a gas
valve in the system?? Not sure but I think it is an all Electric.

Joe; If it is all all electric, you should be able to jump the main
switch and the elements should glow. If they do, don't leave the jumper
connected or the power plugged in, It seems like there is an open in
your heating system. ( By the way;---if your system is all electric, you
probably don't have a thermocouple but a Bi-metalic Strip as a switch)
It still can be jumped. If so, it can probably be cleaned up. If it is a
Gas System, Scout has you on the right track. GOOD LUCK!

Hey Thom,

It's a gas stove. I'm going to pull loose the tc from the valve and
meter it soon. It's a cool system when working properly, if the flame
is blown out then the gas is shut off. Same thing....... if a kid just
turns the knobs no gas. Safe boating is no accident!

The stove has no pilots, electronic spark ignition. You push in the
valve, holding the electro magnet open, when the tc heats up it holds
the magnet and you can let the valve out and adjust the flame. It may
just be crud in the system, bad connectors ect.

Yeah... I bet they do not cost that much, just a pain in the ass to
replace (I think).
I do not have a manual yet, Force 10 just said they were going to
e-mail me one for free :0)

Haggy,
r u sure that decimal is there? Not 15?
1.5 millivolts sure isn't much.
