Having problems with your Air Conditioners ?

Forced air heater lites but blower run a few minutes and shuts down. Service board blinks seven times. don't have manual


Answers :

Watch The Unit's Ignition Process See If The Unit Is Getting Fire Most Likely It Needs A New Thermostat. The Thermostat If Bad Will Cause The Unit To Turn On Ignite But Will Not Detect The Heat From The Flame And Then Shut Off The Gas To Protect The Home From Carbon Dioxide.
If The Unit Fails To Light At All Check The Igniter.
I Hope This Helps,
Sincerely,
Michael Scott

My Carrier 58WAV136 forced air heater's problem is as follows - Thermostat works fine, when desired temp is reached, the fan motor (blower) kicks on. Sometimes it stays blowing for a couple of seconds, sometimes a minute. Often, the electric heating element will heat up and the gas furnace will light. But, the system will shut itself off within a few seconds and will try all over again. The LED sensor will blink 3 times fast, then one time. I do not have the manual to look this info up. Thanks f

I have a Sta Rite Max E Therm pool heater and when I start the unit, the fan kicks on but the heater never does. After 45 seconds or so, I get a " Service Heater" light. The circuit board had leds for limit switch, pressure switch, air sensors, etc, but none are lit. The ignition contol module has a blinking red led which the manual says is a "ignition lockout" issue. What is an ignition lockout? Do I need to replace the HSI Ignitor? Or could it be something other than ignitor? Thanks

Recently purchased a second hand Carrier Split A/c -Model 42KPC019303 - 18000 BTU. The unit would work for awhile then shut off - fan included - and the green light would blink 5 times at intervals - but the unit did not start back. The sensor was changed and the unit started functioning normal for awhile - and then the problem resumed. Only difference is that this time the light blinks for about 10 mins and then the unit kicks back on. I want to know if this is a normal function, and if it ca
