Question about Whirlpool GH9177XLB Microwave Oven
If everything works, but the microwave oven does not heat, this is commonly caused by a failed magnetron. The magnetron is essentially, the heart of the oven. This is what produces the RF energy that heats your food.
In order to ascertain whether or not you wish to repair the oven, you need to consider the following: 1. The age of the appliance. Is the microwave oven still under a manufacturer warranty. If so, the repair should be performed at no cost to you. If not, you may have to pay for a service all, or attempt the repair on your own to save the cost of labor charges.
2. If you wish to repair yourself, you will need to uninstall the oven from over the range in order to replace the part (you will need to do this anyway, if you decide to buy a replacement oven).
3. You will need to ensure the oven is UNPLUGGED before servicing anything inside the cabinet. You will need to remove the exterior case in order to access the magnetron. There are several websites that you can use that illustrate how the oven is assembled:
searspartsdirect.com pcappliancerepair.com appliancepartspros.com If you've never repaired an appliance on your own before, a microwave oven is usually not a recommended appliance to start with. Some models can be rather involved in taking apart.
4, The magnetron replacement part number for the model you have this question listed under is 8206317. The average cost is about $45-$50. NOTE: This model also has a thermal cut-out (TCO) mounted on the magnetron. The TCO acts as fuse and if blown, will cause the oven to fail as well. You can check the tco by removing it from the circuit and measuring across the terminals. If good, it should read 0 ohms. The part number is 8184951 and generally costs about $25.
You need to decide whether or not the cost of replacement parts and the labor involved is worth the effort as opposed to replacing the entire oven at a higher cost and less labor (other than the installation). Review the parts illustrations at the recommended websites to see if this is something that you may be able easily take apart and reassemble. Its not a difficult process, but it can be labor intensive to uninstall the oven.
If you have any questions, please post back and let me know. I hope you find this information helpful.
CAUTION: DO NOT operate a microwave oven, with the exterior cover off. The voltage inside the High Voltage network where the magnetron is installed can exceed 3,000 volts.

If you look at consumer affairs.com, there are many problems like this with GE microwaves. Not a good track record, experiencing problems with mine as well.

Generally, the most common causes of a failure to heat are:
- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose connection on the control unit circuit board
- bad magnetron or other high voltage part (such as a shorted diode)

is usually caused by either a bad door switch or a loose door switch
mount, which are pretty simple problems to fix.
Even though a door switch clicks, it may still be bad inside.
Door switch or mount trouble is usually caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.
There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.
The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.
Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.
One test that sometimes helps is to gently lift up (and/or push down) on the door or handle as you try to start it. If it works or tries to work, then it's a door switch mount or door alignment issue.
If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa:.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.
If you don't find yours, or if you want to look at it without disassembling the oven, you can download it here.
If yours is not shown at the parts site or manual site linked above, Please reply back with your brand and model number so we can help you.
If you only need a switch, you can order a universal type here for $5 postpaid.
If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases in about a week or so.

The magnetron, which is the device which creates the microwaves might have got damaged. If so, it should be replaced. Magnetron is the costliest part in a Microwave oven, check the price before before servicing it.
I hope this will solve your issue.
If my solution proves useful please accept it.

Found the answer by calling a Sharp technician and they said it was the magnetron tube, which is not worth fixing :( Thought I'd pass this on to anyone that has yet to find out.

Tips for a great answer:
Hello epinvegas - Try reprogramming the unit by unplugging it or flipping the household circuit breaker off. Wait approximately ten minutes and restart unit. If it proves to be ineffective, then it sounds like the microwave has a faulty magnetron, wiring failure or control board. Contact a professional to assist with the repairs.
