I need a new heat shield, if that is what it is called? It is the small square piece on the right side that now has a hole in it causing the oven to spark when cooking. Can I get this part locally.Houston...

It is known as the Wave Guide Cover. It is actually very important, stopping the contamination from the cooking food/liquids entering the magnetron and damaging it.
It should be available via an appliance repair dealer.

While heating something up it started make noise like it was shorting out, I immediately unplugged the unit. What could this be and would it be repairable

Hi and welcome to FixYa. I am Kelly.

Most of the time when the microwave is in use and just quits either the Power Diode or the capacitor has failed and blows the fuse inside the cabinet. (Yours is probably NOT blown.)


Location Item 19

Capacitor: (Location Item 20 above link)
Since you unplugged the unit before the thermal fuse blew you were very wise: (Item 28 of interior diagram)

With the unit unplugged and the chassis cover removed the fuse will be located at the end of the power cord lead in a fuse holder. The fuse is usually a 15A 250V slow-blo fuse. Just replacing the fuse will normally result in the fuse failing yet again.

STOP! Before going any further you must hold a well insulated screwdriver back on the handle and short across the High Voltage Capacitor at least 3 times! Failure to do so could be the start of a very bad day in the form of a horrible shock.

Next you disconnect one side of the cap including the power diode wire. With an analog meter set on R x 1,000 read the Cap terminals watching for a jump. Reverse the meter leads on the terminals and watch for a jump EACH time you reverse the test leads on the CAP terminals.

No jump = bad cap.
Constant resistance across the cap = bad cap

Lastly you check the power diode with the meter on the same settings R X 1,000. One direction will read full continuity (ZERO) and reversing the leads will read infinity. (no reading)

If the diode reads open both ways = failed
If the diode reads (ZERO) both ways = failed
It must read continuity in ONE direction only.

After finding and replacing the failed component then you can change the fuse and test the microwave.

There is a very very remote possibility that a door switch has failed but given that your microwave failed while in use I seriously doubt you have a door switch problem.

As far as finding replacement parts for your microwave nearly every appliance parts store will have what you need if you walk in with the failed part in hand. Most of the time they will walk back and grab the part you need without even digging in the parts books.
These are the most common failures when a unit quits working while in use. Yes I believe your unit is repairble at a very reasonable cost.

Thanks for choosing FixYa.

I think I need to replace a fuse in my Whirlpool Microwave oven, but I can't find where the fuse is located?! Help!

There is usually a 125V, 20 AMP line fuse inside the microwave, mounted at the point where the power cord enters the back of the unit. Unfortunately, you will need to uninstall the oven (if this is an over the range model), UNPLUG it and remove the exterior case to access. The case comes off in various ways depending on manufacture and model. If the model number you listed this question under is correct, you have THREE possibilties that may cause a complete loss of power: 1. Line fuse 2. The Oven Cavity Thermostat. 3. Thermal Cut-Out (Thermostat) for the Magnetron. The line fuse is connected in line with the power cord inside the unit and is listed as part of item 28 under the "Interior and Ventilation" parts heading. The thermostat for the oven cavity is listed as item 29 (part number 8183703) under the same parts heading. The thermostat for the Magnetron is listed as item 15 under the "Magnetron and Turntable Parts" heading. The part number is 8183698.

I would recommend you check the fuse, first. This the easiest and least expensive repair. It is also the most common. If you managed to overheat the oven any time recently, you may want to check the thermostat(s) to see if it is still good, next. They should read 0 ohms when measured out of the circuit across the terminals.

If the line fuse is blown, you can usually purchase a box of fuses at a hardware store for just a little more than what the manufacturer charges for a single fuse. 125V, 20AMP Ceramic Slow Blow fuses are recommended.

If you have any questions, or need additional assistance troubleshooting, please post back and let me know. I hope you find this information helpful. NOTE: Baked potatoes, steamed vegetables and popcorn are notrious for causing high humidity and/or overheat conditions in an oven cavity. If you find any of the thermostats tripped or blown, remember to allow the oven cavity to cool by leaving the door open between cooking items. This should only take a few minutes. Repeatedly heating items one after the other can cause high humidity and heat which may cause the thermostats to trip. Some of these thermostats reset themselves, others you need to replace.

NOTE: Make sure you take any resistance readings with the microwave UNPLUGGED and the component under test isolated (removed) from the circuit. These ovens can blow a fuse by simply sitting idle. This can occur from any power fluctuations, brown outs, voltage spikes, etc. Or, it could be the symptom of a component that may have failed. If you find the internal fuse blown and replace it, only to have it blow again, you have a more significant problem than a simple blown fuse.

Whirlpool microwave model # MH6150XLQ

Yes, there is. If you go to and type in your model number, you will find the fuse listed under the "Interior Parts" heading as item number 14 (part #815174). You can find appliance fuses much cheaper at the local hardware store. Just make sure it is the correct type and rating (refer to the fuse in the appliance for the information - these are usually a 120V 20A fuse). The reason I mention this site is because they provide excellent part drawings and provide part numbers. There should also be a wiring diagram located behind the control panel to assist you in troubleshooting. Please go to my profile and use the "Ask Me" feature if you require further assistance. I hope this helps you.

XL1800 GE Spacemaker Microwave oven "dead"

It's not good to run ANY microwave with the oven cavity empty. The items you place inside to cook or heat up act as a "load" and help to absorb/dissipate some of the RF energy. Your microwave has several thermstats installed that will blow in an overtemp condition. If you're lucky the Magnetron is still intact and only a thermostat has failed. The thermostats are small cylindrical devices mounted near the magentron and the oven cavity. They act as fuses and must be reset if blown. Go to and select "Parts & Accessories". Go the bottom of the next page and type in your model number. On the Search menu page select the second menu and type in "thermostat". There will be a series of thermostats listed with helpful drawings on where to locate them. I would advise you to check these drawings first and see if you can locate the thermstats to determine if they are bad. The thermostat should read a short (or very low resistance) if it is good. The part numbers are as follows:

Duct Thermostat (Item 27) ----------WB27X10714
Plate Thermostat (Item 115) ------- WB27X10713
Bi-Metal Thermostat (Item 110)-----WB27X10788

They all cost about $15.00 a piece.

Some additional advice: Make sure you unplug the microwave before servicing. If you are not savvy when it comes to electronics, or have never worked on a microwave before, it may not be adviseable to work on this yourself. Voltage potentials inside the High Voltage section of a microwave oven (where the Magentron is located) can be dangerous. There is a large capacitor that can store a charge and can be a shock hazard.

I hope this isn't discouraging to you, I just wanted to make you aware of some of the possible hazards associated with this appliance. I hope you find information helpful, and let me know if you need further assistance.

PS The alternative if all the thermostats are good, would be to check and/or replace the magnetron. (Item 73, Part #WB27X10305 at $115.00)
