HVAC: Indoor Blower Fan not turning on Automatically?

Ac Systemjdstorer12 asks:

Hey guys, having an issue with my A/C system here. To start, I’m an apartment dweller so I can’t really tell what the deal is with the outdoor stuff as I don’t know which one it is fyi, but on to the point. My indoor blower fan is not turning itself on automatically. If I turn the system on, with the fan on AUTO, the fan will never spin up, but the A/C does make noise like it’s doing something (sorry for the laymans jargon but I’m not the most experienced with HVAC stuff.) Also if I try to switch the fan to ON after the A/C is already switched to ON, the fan still does not turn on. However, if I switch the whole thing to OFF, switch the Fan to ON, and then switch the A/C back ON the fan spins up and all is OK. If I switch the fan to AUTO at this point it will stay on like it’s supposed to until it reaches the desired temperature, at which point the fan will turn off, but will not come back on again. So, any ideas what the issue could be here guys? Obviously I can just call maintenance and get them to sort it out, but before I do I’m curious if it’s something really simple that I can fix myself. Also I’d just like to know for future reference if I move into a house and have to fix something myself. Thanks guys!

BlazeFoam FirestopRectorSeal® Introduces Blaze Foam Firestop Foam Strips for Construction Wall Joints

Blaze Foam™ compressible intumescent strips are designed for head-of-wall, bottom-of-wall and wall-to-wall joints; install 75% faster than conventional methods.

RectorSeal®, Houston,  a leading manufacturer of quality firestop construction products, introduces Blaze Foam, a compressible, fast installation intumescing foam strip for firestopping dynamic and static head-of-wall, bottom-of-wall and wall-to-wall joints.

Blaze Foam is a charcoal-colored, 48 x 5/8 x 1.5-inch (121 x 1.5 x 3.8-cm) polyurethane foam strip designed for easily compressing by hand into construction joints on both sides of the wall up to 1-inch-wide. The compressible firestop increases project productivity, reduces jobsite waste and cuts firestopping labor installation time by 75-percent versus traditional firestop caulking methods.

Blaze Foam was tested in accordance with UL 2079 and ASTM E1966, and is compliant with the International Building Code (IBC), the National Fire Protection Association (NFPA) and all other building codes. The compressible firestop classified as a fill, void or cavity material and carries an F rating up to 2 hours. The assembly has 50-percent movement capabilities, and was cycled 500 times in a range of 1/4-inch to one-inch in tests.

Other benefits of Blaze Foam include:

  • Stays secured without the need for mechanical fasteners;
  • Uses no asbestos or hazardous materials;
  • Expands during a fire and prevents flame and smoke leakage under UL-2079 test standards;
  • Guaranteed to last the sustainable life of the building when applied via manufacturer’s requirements;
  • Requires no maintenance;
  • Intumescent expansion activation begins at 375°F (190°C) and expansion is greatest at 575 to 1,100°F (302 to 593°C).
  • and complements RectorSeal’s full line of firestop products for construction materials, construction joint protection, and wall/ceiling wall penetration sealing in HVAC, plumbing, electrical and other trades .

Blaze Foam has a 10-year shelf/storage life and is available in an 80-piece carton from building materials wholesale distributors. See the product: http://www.metacaulk.com/index.php/rectorseal-blaze-foam/
