Greetings, the ice at the bottom of the cooling coil will keep the unit from starting in cooling mode, there is a defrost sensor there that keeps the cooling function off until the ice is melted.

I need a brand name to go with that model number also, and the approximate age of the unit

.

I am a retired mechanical engineer and HVAC/ electrical/ refrigeration and boiler contractor... with 56 years in this business. The last 20 of those years consulting for major firms nationally..

.

All I ask is please select the***RATING LINK***at the top of your page, that is the only way I am credited through the site. Rating does not affect your charges nor ability to refund if not satisfied.

.

If you need to be coached through a full diagnosis/repair,and wiring etc. for up to two days, and wish to be trained to use test instruments...... that goes well beyond' Just a simple Answer' of course.....rate my simple answer so far positively..and I will deliver that training and coaching to you All on the same dime so to speak.

.

Lacking a positive rating I can spend days helping a person at my own expense and loose my shirt, shorts and socks on the deal.

.

Attach a close up photo of the wiring diagram glued to the inside of the blower access door and I will mark it up with trouble shooting instructions then follow up with step by step training and coaching until you have a solution.

.

Photo must be exceedingly well focused. Use the 'add file ' link next to your send button to get the photo to me.

.

Phone call offers:

If you wish to accept the companies $25 phone call offer,if indeed they send you one, this will go a *lot faster, but it IS100% optional... or we can continue here in this dialog box at no additional charge.
