Question about KitchenAid KHHS179LSS Convection / Microwave Oven

1 Answer

Lights on the underside of the microwave don't come on.

I replaced both bulbs but still nothing. Is there a fuse for the lights? The fan still works and the touch panel still works. Just not the lights

    I have a KitchenAid microwave hood combination. Model # khhs179lss4. I put new bulbs in both sides and they worked for a couple of days, then both went out. The bulbs look like they are okay, I can see the filament in them.

    Help me MicrowaveSvc,
    The large burner element on my GE JP670 electric cooktop would come on and off intermittently. Sometimes it would not come on at all. Other times after it came on and was heating the food it would go off. I replaced the burner element, but it still does the same thing. If the problem is the infinite switch. Where is it located in the cooktop and how do I replace it?

Okay I'm familiar with that model.

We see (and repair) this a lot. The problem is on the control panel, which we regularly repair nationwide by mail for $39.95 postpaid in about a week.

At our Web site, you can get details of our service, plus we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

Sometimes this will also affect the exhaust fan operation, too. The lights and fan can be inoperable or stuck on too.

Feel free to contact me directly (and please remind me of your full model number) for more information & help.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Light doesn't go off and microwave doesn't work


follow this steps and fix it. God bless you


  1. Inspect the power cordUnplug the power cord and check for voltage at the outlet. Also inspect for damage, shorts, or burn marks that can be a possible safety hazard.
  2. Bad door switchIf your microwave does not work at all and you know everything is plugged in properly and the outlet is functioning, then also check the door hooks and the door release button. Using a volt-ohm meter on RX1, check your terminals. When your microwave door is closed you should have a reading of zero. Once the door is open the reading should change to infinity. If these readings do not match up, replacement of the door switch is necessary.
  3. Blown fusesTo determine if your fuse has blown out, which may attribute to your microwave not running, you need to pull the fuse out using a pair of fuse pullers. Lay it down and using a volt-ohm meter on RX1, check both ends of the fuse in question. If you do not get a reading of zero, then you will need to replace the fuse.
  4. Bad fan motorLocate the fan and remove the leads. Again using the volt-ohm meter on RX1, check the terminals. If an infinity reading is displayed, it means that the fan has gone bad and requires replacement.

  1. Light bulbIf your microwave light bulb is not working, perhaps it has blown. The first step is to replace the bulb and power on the microwave. If this does not correct the issue, the next step is to check the socket and wiring to verify if that is the problem.
  2. Light bulb socket & main control boardIf your microwave light bulb is not working after the installation of a new bulb, check the light socket as well as the wiring to ensure they are properly operating. If these sources are functioning properly, the next step is to check for a faulty control board as a possible root cause to your microwave light bulb malfunction.

Turntable, lights and fan inop


I'm guessing that nothing is working...is that right? If so, first guess is the breaker or an internal fuse. Nearly all units have them. You don't say what fuse you checked. Unplug the unit, remove the bulb and see what is in the socket. Next, open the breaker and then turn it back on. This will reset it. Something caused this.
