<div dir="ltr">Hello Wrenches,<div><br></div><div>I recently assessed a 22 year old Trace 4024. During bulk charge mode, I noticed that the charge would go from about 18A down to 5-6A every 15-20 seconds, and then repeat the cycle. I observed this for about 5 minutes relatively consistently I also noticed the body of the 4024 was very hot, and I couldn't feel a fan moving air through it. </div><div><br></div><div>I put a fan on it and blew air over the body of the inverter, trying to direct it through the machine. While I did that, I never observed it drop out again over about 5 minutes, so I'm assuming that there is an internal cooling fan that has gone out.</div><div><br></div><div>It's been quite a while since I opened one of these up. Does anyone know what's involved in replacing a cooling fan on one of these? Is it worth it on a 22 year old inverter?</div><div><br></div><div>Thanks in advance<br clear="all"><div><br></div>-- <br><div class="gmail_signature" data-smartmail="gmail_signature"><div><br></div><div><font color="#305A78" face="'times new roman', serif"><br></font></div><div><br></div>Mac Lewis<br><br><span style="font-family:'Times New Roman';font-size:medium;color:rgb(255,153,0)"><b><font face="Arial, Helvetica, sans-serif" size="3"><p align="left"><font color="#000000" face="Verdana, Arial, Helvetica, sans-serif"><span style="font-size:small"><span style="font-family:arial;font-weight:normal;color:rgb(48,90,120)"><font face="'times new roman', serif">"Yo solo sé que no sé nada." </font><span style="font-weight:700;color:rgb(104,104,104)"><font face="'times new roman', serif">-Sócrates</font></span></span></span></font></p></font></b></span></div>
