I have a whirlpool gas range that reaches the temperature then cuts off but keeps coming on every couple of minutes and repeating that cycle until it gets so hot that it cuts off completely. Before this I replaced the spark module board. any advise??

That sounds like either a fuel issue; too rich, or an air leak in the manifold.
If it were an ignition issue, it woukd cut out, not run rough.

On any gas appliance there is a high and a low limit temp stat which could be indipendant or on the gas valve it's self, that is faulty.
When the oven reaches temp, it cuts out. sounds like faulty over heat stat.

there is a copper pipe over the flame burner, clean this up. this controls the gas supply for temperature, also there is another line on some models separate from this one that tells if the gas has been ignited and keep the supply going or shuts of gas if no heat is detected. this will need cleaning to, oven cleaner and a brillow pad metal type is best to use to clean them, also clean the grill were the gas comes out as if these are blocked the gas will not heat the sensors up.

takes a long time to run the rediness test since there are 6 different tests to complete...

i would guess that you are having a problem with the optical sensor inside the pump housing. it is suppose to sense when the water is clean or dirty and allow the unit to continue washing or advance to the next cycle.
i have seen these test good but be just out of calibration enough to cause long run times.
you can try to change it yourself or have the service company try that instead of a new board and panel.

By the parts diagram, it looks like you have a glow coil type igniter . Generally when the oven wont keep temperature, the igniter is failing to reignite the burner. The burner comes on till it reaches temp then shuts off until the temp falls below a certain temp then comes back on until it reaches temp again and so on and so forth. Most of the time the igniter has a very small crack in it and doesn't begin to fail until it cycles several times. I would check the igniter and the safety valves and coils on the valve

the average life for ranges is about ten years. With the issues you have you are looking at at least 200 in repairs, I would replace. Sorry

looks like operating normally...

the fridge as it reaches it's temperature shuts the compressor off and then after a few minutes..the fridge would increase temperature again and would turn back the compressor again.

its the thermostat which is cutting on and off the compressor.

and i think it is normal. based on the temperatures that you indicated..it is cooling very well..0 F in the freezer and 40 in the refrigerator... that's good.

The technical jargon is,.....:
In order for your gas oven to work this is what has to happen: 1. when you turn on the oven, the range sends 120 volts to the glow bar igniter. 2. as the igniter heats up (and starts to glow) it starts using more electricity. 3. when the electric use reaches a set amount (say 3.2 amps) the range knows the glow bar igniter is hot enough to ignite the gas, so it then releases gas through the gas safety valve. 4. when the thermostat tells the oven controller that the temperature has been reached, the control cuts power to the igniter, cutting the amp draw down, causing the safety gas valve to close. 5. process repeats to hold oven temp until you turn off oven.

So,..........the solution is:
most likely your oven igniter burnt out. Find your model number, usually on the range frame just behind the lower drawer or broiler drawer (depending on if it is a self clean gas range or not) and order the correct igniter and replace it.
