Iffy dehumidifier? We can take care of that!
When you walk into your basement, you'll know if your dehumidifier is working properly or not. If it is, you should feel the air that is dry and feels relatively cool. If it's not, you'll probably pick up the must and maybe even an unpleasant smell. But does this mean your dehumidifier is broken? Not necessarily; it might just be in need of a tune-up. Here is how to fix a dehumidifier that isn't performing up to snuff.
First, you'll want to consider whether or not your dehumidifer is simply too small for the space you have. You can usually tell by a simple test: is this the first time you've used a dehumidifier of that size in your home? If so, then this is a possibility. However, if the dehumidifier has worked well in the past, it's time to check it out and make some repairs.
Note: Make sure that you take out the power cord before attempting any of these repairs. Needless to say, it's a very necessary precaution.
Remove the cover of your dehumidifier and identify the condenser and evaporator coils. These will probably look like they're in need of a good cleaning, which is exactly what you'll want to do. Check your condenser especially to make sure that it hasn't been clogged with dust or dirt. Also, the fan motor bearings might be in need of lubrication - now is the time to drop in a metal lubricant to make sure that it is running smoothly.
Your next option to tune up the dehumidifier is to check the "humidistat" with what's known as a Volt-Ohm meter. You might have to pick one up at your local hardware store. Setting your meter to the RX1 scale, attach the leads on the meter to the humidistat (to what's known as the "terminals"). If you need help with this step, be sure to consult with your hardware store or outsource your dehumidifier repairs to a professional.
The humidistat should register 0 Ohms through a limited range - if it registers through the entire range, there's something wrong with the humidistat and it will need to be replaced.
Once you've made these repairs and the dehumidifier still isn't working, you'll have to consider replacing it or finding a professional to work on it for you. Remember that a dehuimdifier is important to maintain the quality of air in your home; don't procrastinate fixing it.
