Question about Ovens

1 Answer

I have an Admiral Oven, model A68HK-6TXW. Press button for Bake and the oven fan turns on but the bake relay on the relay board does not close. Same problem when trying Broil, again broil relay does not close. Fan turns off after about 30 seconds. Is it a failure of the Relay board or Control board. Each relay has 240Vac across the contacts indicating it's getting power. All connectors have been verified tight on the relay board.

Testing and replacing the power relay A defective relay can result in a variety of symptoms:

  • A relay with its contacts welded (stuck) closed would result in the oven coming on as soon as the door is closed or the power being stuck on high no matter what the touchpad setting.
  • A relay that doesn't close (due to defective contacts or a bad coil) would result in no heat and possibly other things like the fan and turntable not working as well.
If the relay is totally inoperative, test for voltage to the coil. If the voltage is correct, the relay may have an open coil. If the voltage is low or zero, the coil may be shorted or the driving circuit may be defective. If the relay makes a normal switching sound but does not correctly control its output connections, the contacts may be corroded, dirty, worn, welded closed, binding, or there may be other mechanical problems.
Remove the relay from the circuit (if possible) and measure the coil resistance. Compare your reading with the marked or specified value and/or compare with a known working relay of the same type. An open coil is obviously defective but sometimes the break is right at the terminal connections and can be repaired easily. If you can gain access by removing the cover, a visual examination will confirm this. If the resistance is too low, some of the windings are probably shorted. This will result in overheating as well as no or erratic operation. Replacement will be required.
The resistance of closed contacts on a relay that is in good condition should be very low - probably below the measurable limits on a typical multimeter - a few milliohms. If you measure significant or erratic resistance for the closed contacts as the relay is switched or if very gentle tapping results in erratic resistance changes, the contacts are probably dirty, corroded, or worn. If you can get at the contacts, the use of contact cleaner first and a piece of paper pulled back and forth through the closed contacts may help. Superfine sandpaper may be used as a last resort but this is only a short term fix. The relay will most likely need to be replaced if as in this case the contacts are switching any substantial power.

Moffat oven fan wont turn off. just keeps blowing cold air but eveything else is working


Stove will not turn off CHECK

Temperature Control Thermostat


If the oven won't turn off the oven thermostat is often the cause of the problem. The electrical contacts inside the oven thermostat can weld themselves together and then the oven won't turn off. If this happens, turn off power to the entire appliance at the household circuit breaker or fuse. The oven thermostat usually cannot be tested and must be replaced if defective.

Oven Control Board


The oven control board has a set of relays that turn on and off power to the bake and broil circuits according to the customer settings and sensor input. If the oven won't turn off it could be that one of the relays on the oven control board is shorted closed, providing voltage to the heating circuit. It can be dangerous if the oven won't turn off. Don't leave the oven unattended without turning off power to the oven.

Relay board:
Some ovens are equipped with a relay board. This circuit board has several relays which control the switching of electrical current to the oven heat source. If the oven won't turn off it may be that one or more of the relays on the relay board have failed. If this happens replace the relay board. The relays on the board are not sold separately. ALSO CHECK THE BAKE AND BROIL ELEMENT.

My upper oven/ convection function on my dacor ecs230b will not heat


Bake and convection bake settings both use the bottom bake element to heat. It would be unusual for bake to work without conv. bake working. You also have pure convection which uses a different element surrounding the conv. fan on the back of the unit. If you press a feature and nothing happens it's the touch pad. If it comes on then turns back off it's probably the ERC (clock). If it comes on and wont heat only in pure conv. possibly an upper relay board or element problem.

Thermador double oven / Bake wont work /FC code flashed once


I found I have this exact problem. Same bake preheat issue: I can bake if I set broil first. However, the oven doesn't work if I press bake first. The control board has already been replaced a couple times over the years. Is this another replacement??
