I set the upper oven to bake at 400 degrees. After 45 minutes it read 305 degrees and never went any higher. The lower oven works fine. Tried re-calibration, but did not resolve. Suggestions as to cause?

First of all, most oven thermometers move very slowly compared to the electronic sensors and controls on the oven. To make sure you are getting an accurate reading, the thermometer should be in the center of the oven, the oven should be preheated, then wait another 20 minutes after the preheat beep. If the temperature is less than 35 degrees higher or lower at this point, it can be adjusted via the controls. Usually on GE ovens you press and hold bake and broil at the same time until SF comes up in the display. Then press bake, then use the arrow keys to raise or lower the temperature setting. If the temperature is more than 35 degrees off, you may have a bad sensor, bad control board, or other problem.
If you are monitoring the oven temperature with an analog style thermometer you may actually be ok, but seeing the thermometers slow reaction time.
Some newer ovens actually do pre-heat beep prior to reaching temp in an effort to conserve eelectricity.
A good home test is to try your oven at several different temps to see if there is any variation in internal temperature. Try it one day on 300, the next at 375 and another day at 450. Give your analog style thermometer time to catch up (usually just about 15 min) and leave it on for a half an hour to see if the temp maintains.
Also Beware of aluminum foil AND THE NEW OVEN LINER MATS as they can alter oven performance bay absorbing and blocking the ovens natural heat radiation and convection air flow currents that happen in all ovens, not just convection models.
Another interesting fact is that older ovens used a thermostat in them that operated much like your thermometer and was very slow to react making the oven typically about 100 degrees hotter than where the customer set it. This was just a fact of life before the advent of electronic temperature management and became noticeable when people began trying to bake older "hand me down" recipes in the newer ovens with less than stellar results.
You can mimic the older oven performance by preheating the oven about a hundred degrees higher than called for and after it reaches temp, re-set it to the correct temperature and put the items in right away.
If you find your temperatures fluctuating ask your servicer to replace first the temp sensor and as a last resort the control board as this part is usually pretty expensive.
Good Luck with this!
has the oven got a fan on it. if so then maybe fan is faulty.
if convection oven then maybe one of elements is faulty
or the thermostat is a problem

If both baking and broiling element do not heath above
a certain temperature instead, then the part to be replaced is the
temperature probe, still located inside the oven cavity.
If the part that is not heating is only one element, then you may need to replace
Before replacement the element can be tested
removing it from the cavity and reading Ohms at the element terminals,
with a multimeter set at Rx1. Disconnect power before removing the
element. In this case, selecting only baking or only broiling (depending on what element is faulty), the oven will work normally.
If the oven is a gas oven, then you have no element. In that case if the oven burners are working, replace the temperature sensor.
If replacing the temperature sensor does not help, then replace the oven electronic control.
Jim, A couple of questions... What makes you think the oven is off that far? If you have a set on the shelf dial type thermometer, throw it away. They are never accurate and generally read 50+ degree too low. I recommend the "biscuit test". Which is simply a cheap can of "hit on the edge of a counter top to open" biscuits and see how they bake with the instructions on the can. Make sure you allow the oven to preheat for 20-30 minutes (always but especially for this test). To change the oven setting press BAKE, then run the temp up to 550 then immediately press and hold the bake pad for 10-20 seconds. The display should read 0 (zero) you can then use the up down arrow pads to adjust, hit bake pad again and then "clear" when done to lock it in but, you can only go up or down 35 degrees. If it is truly off by more than that you would need to change the main oven control board and oven sensor.
hummmm this sounds similar to what is happening to me. I am praying someone will have a solution, I don't want to have to explain to my daughter who is going to be 4 tomorrow, why I can't bake her cake.
Could be a couple things. If your machine is actually failing either a control board or an oven sensor.
Also measuring the temperature can only be done by a tech unless you have a special tool. Oven thermometers are inaccurate. Plus most ranges should vary temp between 50-75 degrees unless has a feature or the more recent ones keep it between 15-25 degrees.
Try the biscuit test, buy some biscuit, brand not important, i just say pillsbury. Cook exactly as recommended on package. If results are a little overcooked or a bit undercook try a feature called Adjusting the oven temperature or Calibrating the oven. This can be done by following the instructions in your book.
Maytag.com click support click manuals put in model MER5775QA (notice i took off your models S) open the Use guide, page 14
I have just checked the baking guide in the manual and have found that it may not be us after all. (Maybe this is why they telll us to read the whole manual. Well, I never have) According to the cooking time for Baking, the range is very extensive. For example, an angel cake at 350 could take from 28-50 minutes, buscuits at 375-400 could take 8-16 minutes, layer cakes at 350-375 could take 25-40 minutes, pound cakes at 325-350 could take 45-70 minutes and fresh pies at 400-450 could take 35-60 minutes. Basically, the baking directions on the box means absolutely nothing to use Amana oven owners. We have no choice but to cook our food or baked goods until they are cooked, whenever that may be. :) Linda
