GE Spacemaker over the range microwave - no heat, just fan
My GE Spacemaker JVM1533 has begun to act strangely. The panel seems OK and all the timer functions work, but when I turn it on, only the vent fan turns on, instead of the heat and the turntable. This happens regardless of what the vent fan control is set at. I've seen a lot of problems listed on the site that ask about 'no heat' or 'no fan', but nothing like this. The fan has taken over the micowave! Thanks in advance for your help.

A common symptom of a failed magnetron is a failure to heat with everything else (magnetron fan, stirrer, timer, etc.) working fine. Check the GE manufacture date for the unit on its nameplate to determine the age of the magnetron. For GE models of the past, magnetrons had a 10 year parts replacement warranty. Magnetrons can be expensive, so you need to weigh all your options, i.e., repair versus replacement, before you commit to one solution.
Hello there: what this is trying to tell you is that your control panel is starting to go out due to a failure in the controle assembly yes it is feasable to replacethe panel youwill just have to contact the manufacture of the microwave and get a replacement panel/ controle board ok I hope that this is very helpful for you Best regards Michael
Your microwave turning on by itself is a "self preservation feature" of the GE Profile Advantium and maybe some other models. Read the manual, When your over the range oven gets warm enough, for whatever reason the venting fan comes on until a satisfactory oven temperature is reached. You are not permitted to shut the vent fan off. Also it seems a temperature near room temp must be achieved before it shuts the fan motor off, it is very annoying. We had to return our Advantium because of fan noise. I configured the ovens vent fan to the recirculate direction because we do not have a vent duct that exits the house over our range. When the vent fan acting as the ovens cooling fan automatically turned on we would have to leave the house to hear each other talk. Too bad we really liked the oven other than that major problem.

IT COULD BE A NUMBER OF THINGS RANGING FROM DIODES TO CAPACITORS TO YOUR MAGNATRON OR THERMOSTAST OR TRANSFORMERS. IT'S DIFFICULT TO DIAGNOSE WITHOUT SEEING THIS MICROWAVE. YOU MAY BE BETTER OFF GETTING YOURSELF A DIFFERENT ONE.
check the circuit breaker first it may be the fuse is blown The fuse may be located behind the grille following the power cord on the rside of the unit. it may be a bad thermal fuse or oven thermostat.
It is a door switch problem of some sort. I have two Sharp R-1611 units that do the same thing. The light and fan come on, but not the heat, thank goodness.
I am going to replace it since the plastic for the case and door is cracked in numerous places. I have spent several hours researching microwaves online have not a single clue what to replace the Sharp with. Seems like every vendor has very good units and very bad units. I guess you just pay your money and take your chances.
