Jayp September 13, 2015 for Model Number MER5755QCB My oven is not heating at all. Burners work fine. I tested both elements for conductivity and both worked fine. I wanted to confirm I don't have a 74008715 SWITCH, LIMITER THERMAL in my unit but according to specs online I do. I checked what may be a close fit for a thermal switch for conductivity and it came back fine as well. Any idea as to where to go next?
1 Answer Hello JayP. Yes, you have a thermal limiter 74008715. If it is good, then you will need to replace the control board in the unit. Read More...
Clay August 08, 2015 for Model Number MERH865AS16 Our van heats VERY quickly, and the signal sounds when it reaches the desired Preheat temperature, but the oven element does NOT TURN OFF. It will heat until the breaker trips...is this a bad control board? A bad thermal limiter?Or a band thermostat ? Any Ideas?
1 Answer Clay, This issue would be caused by a relay on the control board that is sticking and not allowing the unit to cycle. Read More...
Jack July 17, 2015 for Model Number Werp4120ps3 I have tried everything to change the lower element in the oven but I just can't seem to locate it. where do I access the bake element? I've had all of the covers off and I have no idea what to do next.
1 Answer Hello Jack. Looks like the left body side will have to be removed to gain access to the hidden bake element. There will be screws down the back and a couple across the top of the body side. When they are removed, the body side should lift off of clips or tabs across the bottom. The you can access and remove the element out of the left side of the unit. Read More...
Sally March 14, 2014 for Model Number mer5875ras 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.
1 Answer Sally, 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. Read More...
Andy February 13, 2014 for Model Number AER5715QAQ My oven does not heat up. The oven only gets to about 160 and that takes about 2 hours. Any thoughts?
1 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. Read More...
Todd October 04, 2012 for Model Number mer5755qcb 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.
1 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.. Read More...
Dennis F. May 31, 2012 for Model Number mer5755qaw My question is how do you locate the thermal fuse. I need more information.
1 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 switch. 4. Remove screws securing high limit switch. 5. Reverse procedure to reinstall switches. Read More...
Dennis May 30, 2012 for Model Number MER5755QAW Thank you for answering my question yesterday about trying to locate the thermal limiter switch. I have already taken the back off the stove three times and have serched to find the switch location with no results.It apparently is not where the drawing shows it. On my model, is it possible the switch is in a different location - or - could my model have a different type of switch or fuse or protector to look for? PS - This problem all started when I replaced my burnt out bake element(purchased from your company). After I installed it, neither the bake or broiler element would heat up - leading me to believe leading me to believe I had a blown fuse or a bad thermal limiter (per your drawing and phone contacts for help) Thanks so much for any help you can give me!!!!
1 Answer Hello Dennis. The only other location is under the cook top panel of the unit. You can raise the cooktop to saee if it is located there. Read More...
Dennis May 29, 2012 for Model Number MER5755QAW I am looking for the thermal limiter switch part #4097237 your diagram is not specific enough on the exact location. Another questioner asked the same thing but the answer refered them back to the same drawing which is not at that location on my stove. Is there another drawing or should I look for another part/location. Thanks for any help you can give me.
1 Answer Hello Dennis. The thermal limiter 74008715 is located on the back of the unit. You will need to remove the back panel to access the limiter. Read More...
David D May 27, 2012 for Model Number mer575qaw 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.
1 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 Read More...
