how do I know if it my thermal limit switch is bad? I have replace oem board and terminal block. my oven and stove top don't heat up. I hear my oven click but no sign of heat.
To test the thermal limit switch, you will need to do a continuity test on the thermal switch. If there is no continuity then the thermal switch would be faulty and need to be replaced.
My oven does not heat up. The oven only gets to about 160 and that takes about 2 hours. Any thoughts?
Answer Hello Andy,
The first thing you need to do is to flip the breaker to the unit off and back on. Then you should check the wire nuts in the junction box where the unit is wired to the home electrical power supply. If these check out good, you will either have a bad thermal limiter 74008715 or a bad relay on the units' control board.
I cannot see the thermal limiter. The back is off and I've searched the whole backplane. How far above the terminal block is it? 6 inches, 12 inches? more? I know it should be there but I can't see it.
Answer Todd, Your range does not have a "thermal limiter". Your range may or may not have a "high limit" switch (most "free standing" ranges don't. but here's a little help " Oven High Limit NOTE: Requires removal of oven from installation position. 1. Turn off power to unit.
2. Remove lower rear access panel. 3. Disconnect and label wire terminals connected to limit switch. 4. Remove screws securing high limit switch. 5. Reverse procedure to reinstall switches." If the high limit opens it will shut off power to the control/clock, and resets when the switch has cooled down..
My question is how do you locate the thermal fuse. I need more information.
Answer Hello Dennis. This is exactly what the manufacture says about replacing the thermal switch 74008715. 1. Turn off power to unit.
2. Remove lower rear access panel.
3. Disconnect and label wire terminals connected to limit
4. Remove screws securing high limit switch.
5. Reverse procedure to reinstall switches.
my oven bake light flashes, if you reset the oven it goes back to normal baking temp. Is it the thermal limiter or the temp probe
the control unit is new that is the reason for the replacement.
Answer David, It's not the thermal limiter 74008715 , the oven has to get hot enough to open the circuit, then there would be no voltage into the ERC/Control, or power out to the for the bake and broil element. The oven Temp sensor 12001656 would usually produce an error code (3d11 or 3d21) or should display the oven interior temp. (usually 100 dgrs., that's the lowest temperature calibrated into the control). You probably should start looking for a loose connection at the terminal block on the back of the range, proper power supply at the connection, under a load, and then loose or frayed connections on the harness to the clock. Good Luck and Thanks
