When broiling or baking, oven turns on begins to heat up and error code 4d21 appears. Looked this up and the problem is:

"no/low cooling fan rotation. Check connection at cooling fan. If ok, replace blower. Do not replace control."

We looked with flash light and can see that the fan is blowing, however, wondering if it could be blowing at too low of rpm. If so, should we replace fan or could this be a connection problem? Is this a typical problem and how could it be a connection problem if fan is running?

So, were you able to fix the problem?i have the same error code on my wall ovens. When I turn on oven to pre heat it will start to heat, then shut off and error code 4d21 appears. Feature not available. If I re set breaker several times, it will come back on and work for that time. Next time I try to use oven(s), same thing occurs. Do you know the fix?

Thanks
