I have a whirlpool microwave model WMH31017AS1 it turns on but heat up is there anything i can do

All microwaves have a door open switch that keeps the magnetron from producing microwaves; this could be your problem. Most microwaves have a fuse hidden in the wiring that blows on overload like a lot of food spatter inside. They also have thermal overloads which may or may not self reset. If it died with a big flash you may be out of luck, if not you may be able to locate the fuse or thermal limit and replace it. Another sneaky part is a one time combination temperature and current overload called a thermal fuse:

Self resetting thermal overloads look like this Amazon # B00DM8JGQQ which is a Whirlpool part:
I didn't find a wiring diagram on line for your model, but you may be able to find one; whirlpool generally is pretty good with documentation. Most microwave manufacturers keep consumers as far from doing their own repairs due to the possible dangers involved.
Appliance Parts Store has a pretty good selection of replacement parts

Your full model number would be either GH6177XPS1, GH6177XPS2, GH6177XPS3, or GH6177XPS4 as found on the model tag. I mention that only if you need to order parts.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

mini_manual_behind_grille_small.jpgdee77f7.jpgAt our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

On the tech sheet for our model, trouble code F7 is discussed:

F7 Power to magnetron interrupted

1. Unplug microwave oven or disconnect power.
2. After 40 seconds, check to see whether this solves the problem.
3. Unplug microwave oven or disconnect power.
4. Check cooling fan operation
5. Check resistance of the magnetron thermostat.
6. Check the magnetron.
7. Check P2, P4 and P27 connections.
8. Check wiring to the 1100W inverters and control system. See "Checking Inverters."
9. Check operation of all interlock switches.
10. Replace inverter, if defective.
11. Replace all parts and panels before operating.
12. Plug in microwave oven or reconnect power.
13. If problem persists, unplug microwave oven or disconnect power.
14. Replace electronic control.
15. Replace all parts and panels before operating.
16. Plug in microwave oven or reconnect power.
17. If problem persists, unplug microwave oven or disconnect power.
18. Check for reversed plug connection on controls or loose wiring.
19. Replace all parts and panels before operating.
20. Plug in microwave oven or reconnect power.

I hit the start button on my Whirlpool microwave oven model no. MH7110XBB-5 but got nothing but a click. Any thoughts?

The control board that is located behind the keypad is the problem, I have seen the board develop bad solder connections around the relays. If you are handy with a soldering iron you can attempt a repair, remove top "2 to 6 screws" and remove keypad with control board attached "clipped or screwed in" remember to unplug microwave before you work on it.

Microwave Whirlpool Model: MH1150XMB The keypad numbers 1,2,3,4and 5 suddenly stopped working. any suggestions?

you'll have to buy a new control pad, or if you can solder you may take display out and see if the connections are broke to those buttons and solder them back.

Whirlpool model MH7100XYQ microwave, exhaust fan

sometimes the control board will short out and not let the fan or cook top light work.
if you want to try and remove the control board, look on the back of the board for any burnt off tracers. those are the wiring connections on the board that move power from a wire to a relay.
it is usually easy to see the burnt out piece, and if you can solder a new wire across where the burnt out part is, then it should work ok again.
if you cant solder, then a new control board will cost about 125-150 bucks.
