HEATER HOUSING MELTED AND BURNT

Not from what I am reading. Here is the procedure from the AutoZone repair guide.....

2.8L & 3.6L Engines

1. Before servicing the vehicle, refer to the Precautions Section.
2. Drain the cooling system.
3. Disconnect the heater hoses from the heater core.
4. Remove the thermostat housing bolts.
5. Remove the thermostat housing with the heater pipes, hoses and bolts.
6. Carefully clean the sealing surfaces with a plastic gasket scraper.
7. Remove the thermostat.

To install:

1. Assemble the heater pipes and hoses to the thermostat housing.
2. Install a new gasket to the thermostat housing.
3. Install the thermostat.
4. Install the thermostat housing bolts to the thermostat housing. Partially install the thermostat housing bolts in order to retain the gasket.
5. Install the thermostat housing with the heater pipes, heater hoses, gasket and bolts.
6. Install the thermostat housing bolts and tighten to 15 ft. lbs. (20 Nm).
7. Connect the heater hoses to the heater core.
8. Fill the cooling system.

There is defrost heater which comes on in defrost cycle. defrost heater stays on certain time(lets say 15 min), but lets think it came on to defrost and melted all ice of the coils during 5 min, but we still have 10 more min design for heater to stay on. if heater will stay another 10 min it will warm up your stuff in the freezer, so everything will start to melt. to get around this, all freezers have limit thermostat(defrost thermostat), when that thermostat feels heat from heater, it will shut power off to the heater, so it still in defrost cycle, but heater will be off for another 10 min. When that thermostat get stuck in closed position(does not shut power to the heater when all ice melted out), you will have defrost overheat. so most likely that defrost thermostat needs to be replaced. here is the video how i replaced it on subzero pro series.

cut off that burned wires. You may need a new t-stat

Did you ever figure out how to fix this? Mine is doing the same thing

I just had the SAME problem with an Aloha Breeze Tower model # 02044, mine just buzzed, sparks started coming out and it smoked! Fried and dead -- could have burnt my house down! Scary made in China JUNK! :-( Beware!!!

Same problem i had on the XT24, found out that it was the thermostat shorting out the circuit, changed thermostat and worked ok.

Check to make sure the fan in the freezer compartment is working and not blocked. This delivers the cold air to the refrigerator. The fan should run every time the freezer calls for cold.

When your heater only works on high it is usually
the resistor unit in the heater passage housing. Look for wires ( about 4or 5 wires ) attached to the
plastic heater housing under the dash. It should
have a screw or two holding it to the housing. Pull
it out and you will see several wire coils. If they are melted or broken then thats the problem. On any switch position except high the power goes through these resistors to slow the fan down. Good luck. Neil W.

Hello LILSHAUNLSS5,
I am not sure I understand the description of the problem but let me take a shot at helping you. First off, you obviusly had a short of some sort that drew excessive current , causing a fault and ultimately got hot enough while drawing that excess current to melt something.. Here is where I am a bit confused. Power going to the heater elements comes off the thermostat and onto one side of your elements. If that is where the screw melted, can you remove th eoriginal screw and redrill and tap a new hole for a new screw to be used? If there is any question about the integrity of that termination then I wouldn't mess around with it since anything you do wrong , may result in a fire. So whatever you decide, be careful. If you can provide a picture or sketch of what it is that failed, I may be able to assist you further.
Good Luck,
Regards,
Rick
