We have been having problems with our Wide-By-Side being cool enough on the refrigerator side for a while now.  Called the Maytag repairman and he replaced the Defrost Thermostat.  It was okay for a while but the temp was never under 40.  A little over a month later temp was 50 and no air coming into the frig compartment.  Called again and this time he replaced the Defrost Heater.  There was air coming into the compartment, but again it was never below 41 or so.  Yesterday, got up and the temp inside was 60!  Again, no air coming in.  Called again and was gone while he was there but this time he replaced something electronic (I couldn't read his note).  It was still too hot so I turned the temp control almost to the coldest setting and this morning the temperature is 48.  This guy owned a Maytag Appliance store, but I don't think he knows what is wrong.  Please help!!  I should tell you that I know next to nothing about appliance repair and my husband knows just barely a little more.  I should also tell you that there hasn't been a problem on the freezer side that I know of.

If you could remove the Evaporator Cover in the Freezer and take a look at the Evaporator frost pattern

and check to see if the Evaporator Fan is running.

Sorry I didn't get back sooner - thanks for your email.  The Maytag repair man came back and said that he thought it was a damper switch or something to do with the damper and that he had to order.  So the temp in the frig part has stayed at about 57 for three days.  He came today and took things apart and said that that wasn't it (the damper) because if he held an ice cube to it, it either opened.  But apparently, the coils are iced up again because he is blowing them off with the hair dryer right now.  He appears to be really baffled.  He had said before that this damper thing was the last thing to try.  He says that the fan is working the way it's supposed to, but whenever the unit has come on I have checked and there isn't any air (or very little) blowing into the refrigerator part from the freezer when I hold my hand to the vent in the left part of the ceiling.  He's going to try to find a repair manual, but I'm not holding my breath.

On this unit you will not feel a forceful flow of air through the damper. As the evaporator coils clogg it will deminish to none. If he did test the damper with the ice cube correctly and the door opened and shut then the damper and the control are ok.
It so far sounds like you have a reoccurring defrost issue.

Do you have any itemized billing or receipts that might indicate what parts this monkey has put on there. He doesn't know what he's doing and I hope he hasn't charged you for his ignorance. Sounds like he's replaced you entire defrost system.

He has replaced the defrost thermostat and the defrost heater.  Charged me $90 for the thermostat and $116 for the heater.  He also replace something electronic that he didn't bill me for.  Today when he brought the damper control and that didn't turn out to be the problem he left after defrosting the coils and didn't give me an invoice.

Those charges included trip charge and labor.  I didn't think they were out of line.  I can get a good discount on parts thru whirlpool because I am a Maytag retiree but I wasn't going take whatever he makes on parts away from him by doing that.

since The defrost thermostat and heater come together as an assembly means that when he replaced the Thermostat he had to cut and splice a different one in (hopefully he put one with an appropriate temp. value) Wonder if he changed them both again when he changed the heater or did he just change the heater? I wonder if his crimps or connections were good? soooo many questions.

I wish I knew.  When he replaced the defrost thermostat in May he said he had one on hand and replaced it that day.  Six weeks later when he replaced the defrost heater he had to order it.  So if I understand you correctly when he ordered the heater it was part of an assembly that had the thermostat with it?

yes thats correct. you can't get an exact replacement thermostat without getting the heater too. Let me explain:

Its common in these situations to replace the original with another type thermostat. It would not have the same type connector on the thermostat as the original so he would have had to cut off the connector on the heater and splice the wires together. This is perfectly fine to do as long as he did a good job and as long as the thermostat he installed has an appropriate temperature range (all thermostats aren't the same, there are literally hundreds of different variations) I would hope he installed the new thermostat / heater assembly and not just the heater...some people would have went to the trouble to cut the new heater connector off and attach the old thermostat in order to sell the new thermostat at a later date. Hopefully this isn't the case.
