Weather King: model # 13AJA60A01

check the outside unit to see if it is running. If its not check the run cap which is the big silver round object. Make sure you are getting 240 volts to the contactor;

Check your contact relay, capacitor, and condenser fan motor

Weatherking has five year parts on there equipment. You may just have a breaker kicked or tripped float switch. Check for stopped up drain Shop vac **** out stoppage from the outside drain line for unit. Check breaker. The sound you here maybe the contactor. It energizes from the tsat inside. If the contactor energizes. You have a high voltage problem. Your warranty covers aprts not labor. So call a Rheem ,Ruud or Weatherking dealer. Any of these dealers can handle warranty parts. Rusty Feadback please.

They amke a universal fan. Multi speed reverable. Just get a 1/3 hp and use that. I only carry 1/3 and 1/2 horsepower on my truck. I have been doing service work for 45 years. Rusty

it is either low on freon or the airflow is blocked. check your filter first. then see if the coil is dirty. saying it needs a new coil because it is freezing is an expensive guess unless he did a freon leak test.

Turn the power off ,and check all the electrical connections for loose connection or wires. also make sure these are slow blown timmed delayed and not one-time fuses. Thank-you verymuch!

Unit is over heating and setting the internal limit switch. Capacitor an/or outdoor fan could be failing.

tHATS DEPENDS ON YOUR PART OF THE COUNTRY YOU LIVE. DUE TO REQUIRED INSULATIONS VALUES!

You need a service tech to check out your system. Your compressor may not be starting which could be the reason for the humming noise and no cold air. Dead snake may not be related to your problem.

is it the condenser fan or inside blower???
